I put a b18c1 engine (obd1) into my '94 Civic Si, when the engine was installed, there was a bad oxygen sensor which triggered the check engine light, I got that fixed, but the car still idles erraticly, here's a description:
When I start it up, it revs to about 3800 rpm, then it drops back down to 1500 rpm, then kicks back up to about 3500 rpm, then goes back and forth between those 2 engine speeds.
My first guess was a vacuum problem, I took it to a shop, they did a vacuum test and said the vacuum was good.
Any help would be appreciated
