Another idle problem
I have a 90 bronco 302, when cranking it on a cold engine (not driven for 3-4 hours), it will stall. It seems to only do this if I forget to turn the A/C off before cranking. It starts fine, idles about 1500 rpm for 4-5 seconds. When the, for a lack of a better word, choke cuts out it dies. The rpms drop like a rock. I can crank it the second time and it does just fine. I have begun to expect it to do this so I crank it then wait for it die, crank it a second time and I'm ready to go. Its not so much the problem that annoys me, its the fact that I can't seem to fix it. I have cleaned IAC, tested it (it tested fine), tuned it up, timed it and still no change.

I had the same problem for months. It got real bad two weeks ago. I chased it down to the EGR valve. I removed it and cleened it with spray "intake cleaner". I also cleaned the inside of the throtlebody with the same "intake cleaner". After doing these two things, it fixed up my motor real nice. The RPMs don't drop like a stone anymore. And I don't stall when the engine is cold. And the lowend power "feels" stronger.
You should pull the codes from your computer. I had a code saying the EGR valve was acting up. If I had looked at the codes sooner I would have fixed the problem a long time ago.

My check engine light is not coming on. Would it still have codes stored in the memory. I'll give it a try, can't hurt any.
Thanks, I'll let you know what happens.

I tought it ment the EGR valve wasn't opening. But it acctually ment the EGR valve wasn't closing. Causing a vacume leak, that messed with the idle.
