stumbles on acceleration
Posted: Wed Oct 29, 2008 6:30 pm
PICTURE THIS. 89gt. no codes. Car idles fine, all temps. problem occurs at all temps. Idle speed okay.
WHEN THE THROTTLE INCREASES BY A SMALL AMOUNT [1/16" OR SO] THE ENGINE SPEED DIVES TO ALMOST STALLING.
All main ign. components check fine. All main fuel components check fine. stock intake, stock exhaust
Suspect dirty TPS / IAC valve, but thats why I'm posting.
Its really annoying, b/c the clutch out gas pedal down simultaneous action from a stop would probably cause our bnet drivers to stall the engine. So I launch higher than normal.
All else is fine, drivability is fine, this problem just makes it annoying - EVERYDAY
22mpg+ I've been getting, so... car seems healthy!
Any ideas?
