ctyankeeinok Posted June 25, 2005 Share Posted June 25, 2005 My 91 Camry DX automatic (which I just bought used) runs a bit rough when I am waiting at a light or stop sign. Sometimes it will stall when I step on the gas. It runs smooth in park. I know the transmission was replaced at one time (30K ago?). Is there a relatively easy way to adjust at what point the tranny engages more forcefully? I thought if I could raise that point a little, it may solve the problem. Or, how do you increase the engine idle? I have not worked much on a fuel injected engine. Quote Link to comment Share on other sites More sharing options...
ctyankeeinok Posted June 25, 2005 Author Share Posted June 25, 2005 I did find that the air tube from the air fileter housing to the engine has a pretty serious crack in it. I ordered a new one from the dealer for $65 (ugh!). At least that was cheaper than the other dealer in town who wanted over $80. Unfortunately the cheaper one is significantly closer. I'll drive across town for the cheaper parts. We'll see if this fixes the problem.... Quote Link to comment Share on other sites More sharing options...

Look for traces of black carbon from metal contact to surrounding areas. Coil is under the plastic cover below the rotor. b-t-w, the idle is controlled by a small screw locked by a small nut under the throttle wheel, next to throttle body. Uses a small hex wrench at lower end to adjust in/out after loosening the lock screw. Adjust while engine is off in order to rotate the throttle wheel out of the way to adjust the screw.

ctyankeeinok Posted September 27, 2005 Author Share Posted September 27, 2005 Thanks for the info on the throttle. As it turns out, I replaced the air tube from the aircleaner and that helped. Then I replaced the spark plugs, wires, and rotor. The problem has been fixed. It was mostly caused by the cracked air tube and old wires.
