My buddy has a 92 RS long story short stumbles on acc. idle stals, pops in the intake. Replaced cap, rotor,plugs, wires, did the unplug sensors, see what happens. The only thing that didn't change anything was the IAC valve. I'm pretty sure it's the IAC it's on top of the throtle body. ANY SUGESSTIONS FELLOWS?

codes?

maybe firing order is wrong. may be an issue. make sure the dist. is tight.

possibly timing being off. can really make your car run like crap.

was the wire unplugged when you checked the timing?

rickey86z

what wire? I have V8 carb, no ecm. so no ses light. not sure how to check it????

sloick

get a timing light clip the power lines to the batt. spark plug end to the #1 plug wire as close to the end as you can. find the pointer, should be above the crank pulley, disconnect the white/brown wire along side the passenger fender. start the engine and point the light at the pointer. watch for the mark to line up witht the pointer.
