Having some idle problems...please help, details inside

[noredline]

How do I get to the CPS and adjust it? It does not backfire and there is no smoke coming out of the exhaust what so ever.

Do you have a turbo? Its on the passenger side where the distributor is on the na. Its at the front of the block right behind the thermostat housing. It has a plug coming out of it, and it looks like a distrubtor except without the spark plug wires. Then you need to get a timing light(follow timing light insturctuons), But there 40$ or so if you dont have one already. and to set your base timing. Im not sure exactly what its supposed to be, Ill find out what its supposed to be

It is the turbo model, so where would it be if it's in a different area?

Its where i described. Turbo has a cps, N/A has a distributor. And supra2nr, Im not familiar with the silvia chassis/motors at all, I kust know the n/a ones are slow...lol but anyways When do the flames come? when he gives it gas or lets off? Flames usually mean something is timed wrong, And its dumping too much fuel at the wrong time or igniting the spark plug too late, And if its a swapped turbo Id bet its the stock ecu not liking the boost. Anyways give me a few more details and i can help, like, was it swapped? when exactly does it backfire? and smoke when it backfires?
