I have a 89 ef obd1 with a b18, its not just swapped have had it in for about a year now its had it share of problems but all of those are fixed.. no CEL's. Anyways on cold start up ( this started happening about 3 weeks after I cleaned the IACV and then I bleeded the cooling system ) if I press the gas at all or drive away like while its cold then idle will bounce 1200-1800 over and over until the car warms up then it idles at around 650 which I know is a little low but my idle adjustment screw does not work ( working on getting another tb ). If I let the car warm up cold the idle will be perfect not bouncy or anything as long as I dont touch the gas pedal... Any ideas on it?

 

bump

 

Make sure the TPS wiring is clean and sealed.

bump

 

Can you explain how it is bumpy? Like 1-2-1k every 5 seconds or 1-2 every 30 seconds.

Have you tried a basic tune up: plugs, wires, cap, rotor?

 

New dizzy, New wires from acura. like once it goes to 1800 it will drop to 1000 then go right back up to 1800 so its like continuous...

 

I had an issue like that before, it was due to throttle cable binding since I stuck with the original DPFI throttle cable initially. We had to loop it around because it was so long. It worked like that but every once in a while it would do the idle lump/hunt thing. Even if you swapped throttle cables already it may be as simple as adjusting the throttle cable and hitting the throttle plate pivot with some WD40.
