Trans problems

Ok heres the problem when car sits idle for bout 15 min when you take off the rpms rise but car does not pull quite as had. Car has new clutch exedy satge 2 with lightend flywheel and new fluid also has aluminum driveshaft. could it be that scorched the flywheel or burnt the fluid? whats are your opinions

sure it's not an engine issue?

The motor shows good compression It does have a valve cover leak, still running ka24de the only that make me think that it's the motor is sometimes at low rpms it sputters but as soon as you get above 2500 it picks up fine

That sounds nothing like a trans or clutch problem dude. Once your in gear it has nothing to do with your trans unless its slipping, but this is NOT slipping. Sounds like a vacuum or fuel issue to me. You need to read more into it.

Would it be where blocked off all the Egr crap

sputtering eh? sounds like a vacuum leak




only does it when warmed up eh? eh?






SS

the sputtering only at low rpms. only when in idle then taking of the rpms rise but the car does not pull as hard

check timing.

if you changed all that, it shouldnt be an issue with the trans. unless you messed up the install. has to be something else.

What I've narrowed it down to is the header. While out driving, playin around I slid it off raod and the header is cracked but it is cracked above the O2 sensor. I think that it's pulling in air and the O2 is adding fuel to compensate the air being sucked in. Think thats possible???

yeah that would do it

if the O2 is showing the ECM that the gasses in the exhaust are lean it'll add fuel to comp and try to bring the mix to 14.7:1

wouldn't hurt to seal it with some JB weld as a TEMP fix just to see if that is the problem

if it is new header, if not, then keep looking

I'll try that for a temp fix. Or use a welder to lay a bead over the crack
