1990 idles is erratic
I have a 1990 with a 2.1 in it, the engine idle is erratic. When you barely push the throttle the rpms will bounce. I can't seem to locate the problem. I have unplugged the fast idle valve, unhooked the egr valve also. I am lost and need help
Thanks |

Re: 1990 idles is erratic
Mine is doing the same thing, have you found any answers to the problem yet ? Is yours carbureted or fuel injected ?

Re: 1990 idles is erratic
Have you done any work on your car recently? One of the main causes of a bouncy idle is air in the cooling system. You could try bleeding the coolant. Here is a handy link that talks about the causes of a bouncy idle in a 3rd gen and how to fix the problem. It's pretty specific to fuel injected models though...
Bouncy Idle Fixes In case you don't know about it, here is a website entirely dedicated to 3rd gens. Lots of helpful information here... Prelude3G.com

Re: 1990 idles is erratic
I think 1990 was the last year of carbed ludes.But not all had them. Luzer is right. It's usually air in the cooling system which needs to be bled or the iac valve itself.
