I have been having a strange problem and am not really sure where to start diagnosing.
After the car is up to operating temp, whenever I shift to neutral, if the RPM's are above 2k, the car idles at about 1800rpm until I start again. If I keep the car in gear and wait until the RPM's are below ~1500, then it drops down to about 800rpm, and idles as normal. Everything else seems to be fine with the car's mechanical, just this one weird glitch.... Is it the decel valve? Something else? |

If it turns out to not be the decel valve...
Check out the advance plates and the vacuum canister on the distributor. My car was doing this at one point, and the plates were gunky. Refurbed the dizzy, clean, lube, and replaced the vacuum unit (which was leaky) and it cured my problem. (Don't know which year/motor you have - my 75 2.0 used vacuum retard at idle on the dizzy, yours may not.) But the dizzy might need some maintenance anyway. |
