Alright, my car was running fine except for what I thought was leaking injectors, but they only caused problems on startups, when it was runiing everything was fine. Last week I replaced the injectors with used ones only to have it run very rough. It would stay running, but if I floored it, then it took forever to rev up. I even put the old injectors back in with no change. So this week I decided to just replace everything while I had it back apart. So, I put in new accell injectors and a stealth ram. Well the problem is still there, so i replaced the plugs, wires, cap and rotor but the problem is still there! I have no idea what else to do. It seems to be missing and it takes forever to rev up. Please help!!

Do you have any codes ? You really need to approach this in a setp by setp diagnostic manner.

Does it do this with the Chip I sent you ? Email Me.

 

It does it with the job, but not because of the chip. It does the same thing with the stock chip. I put your chip in after and it was the same. I do not know what to look for, it is very frustrating. I feel that I have replaced everything but the throttle body so I do not know what else it could be. Maybe the injectors harness or something--im lost.

A few things to consider;

What's the fuel psi doing?
What's the vacume reading at idle?
How's the spark?

 

Tim, Whats the TPS and the IAC situation ?

You say its running very rough, and has no power... I almost want to say you have a dead cylinder... Maybe time for a compression test ?

This problem started when you switched to the used injectors, and continue's through now w/ new injectors and the HSR ?

Did it ever happen before the new used injectors went in ? did it ever run ok w.o those injectors ?

gotta narrow down when this started, and possible causes.

It really sounds like a dead hole to me, but you replaced the ignition components so its unlikely its related ignition related.

 

It has never had this problem before. It never did it until i put the used injectors in and continues now with no change. It has to be something that i did between then and now but I have no idea what it could be. I cant check it now cause I am back at school, but I will be going home again this weekend. I did take the lid off the throttle body to celan it up but I do not see how this would cause a problem so I have no clue what I have done.

Maybe the harness to an injector got messed up, have you checked to see if all cylinders are firing?
