using midgrade gas, fuel injector cleaners regularly...new mufflers, starter, battery...used to have to push start once in a while until i put on mufflers, and changed flange then i let it sit for about a week then had to push started it again, not even started flued would do the trick. when i got it started it blew out alot of white smoke and now when im accelerating in second gear at about 3k rpms it spudders and i could have the peddal all the way down and it wasn't going any faster i would just let off and go back to accelerating and it would be fine...any ideas?? please help

 

Bump... i have the same trouble.

 

Is the car leaking coolant into the combustion chamber? Id check that out, and also change the fuel filter if you don't know when the last time it was changed.

 

the 3k power loss thing sorta sounds like a clogged cat. the white smoke thing sounds like your coolant seals are going... time to start saving some money.

mee too but my ecu is fried ......still driveable but...ughh...

 

how do i know if my ecu is bad?and could not having a air pump cause problems?

 

5th and 6th ports are stuck closed...due to no airpump...wire them open and you'll be ok...

 

how do you wire open the 5th and 6th ports, what will it do to your car? How do you know if you need to wire them open? sorry I'm a NOOB!!

 

If you wire them open, you wont have much power below about 3k-4k RPM's. Its still driveable, it just kinda feels like you have turbo lag.

 

thanks man. I was just reading up on what they do exactly. How do you know if there doing the best job they can?
