(ka24de) ok so heres what happines, on cold starts she drives like a champ and pulls great! But once its warmed up and i turn it off and back on, it feels like i have 90 hp. :/ like when im driving normal its ok i guess but the minute i give more then 30% throttle it just gets loud and not go anywhere, like it wants to go but had and anchor on its bumper. I do have a check engine light for codes 32, 33, 34. i changed the knock sensor but im still getting codes for it. any help will be gladly appretiated. (excuse my writing errors, writing this will half sleep)

Sounds like a Coolant Temp Sensor

Maybe you have too much sludge build up lol......JK.

I'd check your temp sensor as well. And check the ecu for codes. It cant hurt.

if temp sensors check ok, check your catalytic converter, that will cause same symptom.

Have you checked your engine timing?

The issue is timing. i redid my distributor and made sure everything was spot on and the problem was solved

Mishkin_707 · 05-26-2012, 11:47 AM

Thanks, I'm going to see if that's my problem, in the 11 years I've owned my car I never have checked or messed with my timing
