alright went to autozone and they did CEL code thing and it said engine running lean. Which the guy told me probably because of clogged fuel injector. I think it could be fuel injector since their are some signs for example
I get a lot of pops in my exhaust maybe because the fuel isn't burnt due to bad fuel injector and I get the pop noise a lot while driving, my quarter mile performance went down, when I clean inside of my exhaust it gets black again pretty fast,takes couple of sec to start my car ( not enought fuel delivery during start up or just bad battery), went starting off in first gear from stop car feels like it wants to die, so I have to start at like 1500rpms most of time for good normal take off, the car does have 52K miles on it so it's possibility that it could be fuel injectors. The only thing that goes agianst all this is when car is idle it's rpms are perfect doesn't go up or down at all it's very leveled. I have injen intake but if that was causing the check engine light to come on it would have came on earlier not after 2 months or so after it's been installed. So what do you guys think ?
