HELP!! New to Celica's!!

[delos23]

Okay, so I have a 2000 Toyota Celica GT-S 6 speed, Now, my issue you is the car likes to bog out, tps ics, ignition plugs, maf, all that has been replaced event he coolant sensor, now i switched out the ecu, and the car will run but acts like ti doesn't get enough gas into it, i need help do i just need the ecu reflashed?

[dead_star04]

Need more info. Any mods? Only when cold, when warm, all the time? Sure it's bogging and not a slipping clutch? There's a lot of stuff to check out.

I do think Toyota had an update for early celicas, something about improving cold drivability, but that would be a dealer job

[party2go]

The GTS does not like extremely hot or humid weather and tends to bog a lot upon start up. This would intensify more if you have a cold air intake.

This.

Sometimes it feels like it doesn't even want to move

Sadly this does happen lol but it passes once the oil temp gets higher hahah

Also clean the MAF like it's a dirty asshole.

[celica651]

damn it.. no wonder my celica has been acting up. it doesn't want to move.

The early GTS's have this issue much more than later models. There is, I believe, an updated PCM and injectors which can nearly cure the cold start issues and dramatically improve engine performance during initial start regardless of ambient temp.

[delos23]

well, I think its more of a fuel issue, im guessing, cause, its acts like its not getting enough gas, if i WOT it takes a few seconds for it to realise what im doing. It will idle fine but once i push that gas in, it takes a few seconds...ALSO It's got a brand new MAF, and It's got a injen cold air intake with a greddy cat back.

[00gtsshocker]

Get 330cc injectors with the 2k Ecu it works great and I have a cai it only feels like its bogging cause of my clutch

[Bitter]

The newer injectors have a different spray pattern for better cold performance and are slightly larger. During cold start it will run a little richer and at full throttle a little richer as well but not much. The newer PCM's are mapped for this, the 00 is not, but the change is small and probably wont' cause problems. Nothing you can't 'fix' with a simple AFR piggy back to take out a little fuel at open loop high throttle.


Or just live with it and drive gently till its warmed up a little.

[jasonc624]

this is probably one of the more relieving threads I've read. I thought my gt-s was having massive problems. It really pisses me off when I'm late for school in the morning and I'm trying to drive fast but its like a stubborn mule.

[Bitter]

Leave 5 minutes earlier and let it warm up a little first.

[delos23]

Okay, I'll try to let it want up and see what happens then.

This is precisely what I do. A light foot on the pedal, 100% of the time. As you stated earlier, once the engine warms up there are no issues with bogging whatsoever, even on the hottest of days.

[GSBoek]

The initial problem with bogging at throttle tip in after a cold start might have to do with the ECU settings with regards to the clutch switch on the clutch pedal. What I usually do is start the car, put it in neutral and release the clutch pedal to let it idle for about 20-30 seconds.
After I do that I can take off gently but normally without any bogging. If I don't do this I usually have to work the throttle to avoid the bogging at the release point of the clutch.

[delos23]

okay so what if its the idle control valve, like symptoms

[ronscelica]

do you have a check engine light? You can have bogging even tho the problem is completely unrelated. My temp sensor plug came out because the clip broke. It threw a check engine light and my car was really hard to start and wouldnt run for shit. Would bog, lost a lot of power, and ran more like it was some seriously clogged injectors.

[delos23]

Yeah I have a cel it flashes at times to witch I herd is a misfire. But the coils are brand new along with spark plugs I unplugged everyone and each one the car shut off. So I did t r dame with the injectors and they all made the engine change except one but the injectors are supposedly new but I found out they are eBay injectors so. I need some injectors. To rule out that.

[delos23]

also I've figure out the bogging issue. now my issue is it doesn't seem like it's getting iou mg enough gas or something. it doesn't seem like it has all the power it shoukd

edit: I went and had my cel check and these are the codes,

0300 Random misfire
0302 misfire in cylindar 2
0303 misfire cylinder 3
0304 misfiire cylinder 4
0505 Idle Control System Malfunction
(already knew that)
0171 System too Lean (Bank 1) Injectors are new?
P1300 Igniter Circuit Fault (Bank #1)
P1305 Igniter Circuit Fault (Bank #2)
P1310 Igniter Circuit Fault (Bank #3)
P1315 Igniter Circuit Fault (Bank #4)

The coils are knew so wtf?!

[navseal345]

Some one please tell me if I'm wrong... But its possible that if you had a bad coil you could of burned up the driver for them in the PCM.

What's a pcm?

Or ECM (engine control module). PCM (powertrain control module). Depends on who you talk to.

Well the car came with two ecu one has a 2 at the end of the serial and the other has a 3 does it matter?

I really have no clue. I currently own a 94 Celica GT, but hope to be getting a 2000-2001 GT-S soon.

[GSBoek]

Those could be all the old codes that were not cleared. If they are new codes then definitely have a compression test. Bent valves could be causing you headaches.

[delos23]

But if it was bent valves then i wouldn't even be able to drive the car hardly at all.
But, I can drive it, I know my cat's clogged

[navseal345]

Rebuild the motor and put all that fancy stuff in there.

[delos23]

yeah, id like to know of a good site to get parts?

You'd be surprised at what how hard you can still run your car with bent valves.

2000 ECM
89666-20082 (Manual)
89666-20092 (Auto)

2001 ECM
89666-20083 (Manual)
89666-20093 (Auto)

2002 ECM
89666-20190 (Manual)
89666-20200 (Auto)

Either or should be fine.

[jasonc624]

Dude give your MAF sensor a super cleaning and it will clear 1 or two codes p0171 will go away more than likely. Be sure to clean every single part of it. If you see any dirt on the q-tip you know youre doing it right. I also have p0300 and p0302 but i get no more bogging.

[delos23]

It's a brand new maf or so its said, i cleaned it nothing changed, it doesnt bog anymore ive said that a few post up, but it just doesnt seem like its getting what it suppose to, it kinda sounds like a subaru with and exhaust idk why it sounds like that, i need to do a compression test, if the numbers aren't good looks like ill be driving it the way it is, and buying some new parts to put in it, I read something about an ecu reflash or something?, i think ill buy another ecu and go from there and some new injectors see where that gets me..

[ronscelica]

sensors... i will put money on it. Check all your connections... if all else fails buy some new intake manifold gaskets spray a bunch of cfoam in there, remove the coils and just let the motor turn for about 20-30 seconds then put it all back together and test it out. oh use shitty plugs when u have the cfoam in there. then put some nice ones in after you get it all running and cleaned out. if you are thinking injectors are bad instead of spending a shit tone replacing them all (cus i doubt all would go bad) put a bottle of injector cleaner in there. when doing all this you may have to clean your plugs a couple times, will probably get fowled. but all this can easily be done in a couple hours. hardest part is getting the gasket. usually takes a day or so from your local autozone.

[delos23]

I really don't know what it is, All most every single sensor has been replaced, TPS Crank and cam sensor, coolant temp sensor, MAF sensor, im running out of things so im gonna do Prussure test on saturday, Also, I have a 2000 celica GT Rebuilding the motor, any tips? any cheap but decent parts i should look into, trying to keep it all oem size, then when its done, im gonna build the gts for some power or what would you guys do?
