I have a 93 3.4L camaro and it keeps cutting out. I just put new o2 sensors in it, a new fuel pump, fuel filter, gutted my cat, egr valve, and a map sensor. But it still keeps cutting out some times and is hesitant when i push the gas pedal. My mechanic said the computer is shot.. Did this happen to anyone or does anyone know if getting a new ecm will fix the problem. i need help asap due to me having to sell my car asap and i cant sell it with it cutting out like this.. Can anyone help me??

 

Is there a check engine like present and have you checked for codes in that case?

Really, there is little chance for anyone to make a correct diagnosis over the internet. Get the computer tested if you feel you must.

 

the light does come on and we did put a computer on it, but it wont clear the codes. So thats why we were thinkgin the comp was shot.

 

does sound like the computer, mine did that, threw a bunch of codes that would not clear, said sensors were bad that tested good. did this happen before you changed the fuel pump or after? reason I ask is I own a shop, guys will change their fuel pump and it wont run right, cuts out anything above idle. I get the car, check fuel pressure and it will be fine at idle, but drops off above idle. Pull the tank, pull out pump and find that they did not put clamps on the short fuel hose from pump to fuel line on module, so it loses fuel pressure there!!!

 

what you explained about the fuel hose, happened before i changed everything. But like you stated first the same thing happened/ happening. I found this ebay is this what i need?

 

is that what i need?

 

I think it's the right ECM for your car!

Ask the seller for more details....... but note: you must use your old chip, because the new ECM don't know if your car is a manual or auto....

 

thanks for the help..
