So here's my problem, hoping somebody can help. I have a 1992 Honda Accord (fancy, I know)... When I start the car cold in the morning the idle is really rough and sounds strange when accelerating. After the engine warms up, this disappears for the most part (sometimes will have an intermittent shaking when I'm stopped)... another thing i've noticed is the tachometer acts a little goofy while driving, it bounces slightly up and down while driving (not a flare type of bouncing, just a subtle bouncing)... any ideas?

Thanks Guys (and maybe gals)

Come on people... with our powers combined... we can figure this out.. or i guess you can, or I wouldn't be asking.

 

You may want to check your FITV since that controls idles at cold.

Check your IACV and clean it out.

Maybe do a tune up as well such as plugs, wires, and cap.

 

search, noob.


kidding, you can disassemble your fitv and iacv and clean them with carb cleaner, if you search there are diys on a few forums, i know theres one on cb7tuner. might as well clean out your egr port too, since its only two bolts to remove it.

another lesser known cause of idle bounce is air in your coolant lines. try bleeding your coolant, or at least check for leaks.
