OK, I'm once again stumped. My car just won't idle smoothly. It sounds like it's going to die, but then revs itself up a bit, then almost stalls again, then revs again... So, I thought it might be a vac leak. I had already replaced all of the hoses, but found that I had leaks on the air intake runner things, where they connect to the plennum. So, I disassembled everything, replaced those hose-type things, and voila! No more vac leak there. Problem is, still not idling right. It's just as bad now as before. One more thing, I slowly brought up the rpms from the throttle body, to listen, and I think I heard a couple of really quiet backfires. Maybe an exhaust leak? Could this cause a bad idle? Thanks.

The cold start injector shouldn't affect anything. I believe the way it works is this: There is a temp sensor on top of the case, on the passenger side, near the front. That senses the temp of the case. If it's cold, it activates the cold start injector. As far as I know, the cold start injector should only be activated when the engine is cranking, and should shut off when the engine is running. I suppose that if the wire to the temp sensor fell off and is grounded, the cold start might run all the time, and who knows, it could do something funky.
I don't think I have any pics of the cold start sensor off hand. I think there might be one on Brad Ander's page. It wouldn't hurt to try and get it working right. |
