Harley sounding at idle

[carrebuilder]

Well the topic pretty much explains it. 87 MK1 and I just cant get the car to idle right. Once Im above 2000 RPM the car sounds and runs perfectly but in the lower section it sucks. Another thing is if i have the car in park or nuetral it idles @ 2000 RPM, then I put in drive and it drops all the way down to 600 or 700 RPM. I checked the vaccum lines and made sure they were ran correctly, but still no dice. The coolent is bled and I just fixed that whole deal. I have meesed with the TPS sensor and it still sounds like a harley. I sounding like a bike tells me that I have 2 misses but I could be wrong on that. the distibutor inew along with the coil and plugs and wires. Any info would be apreciated.

if you were missing you'd have a flashing CEL...

so if it sounds like a misfire, and no CEL, and it smooths out after 2000 rpm when engine vacuum is almost nothing anyways... 99.9% sure you have a vacuum leak.

but w/ all the work that seems to have been done. the question is did you have this problem before everything was "fixed"....?

Well what Im going to try to do and what I hope is that im 180 out so it works but not properly. And yes it work excellently before I had to redo the headgasket.

Definatley sounds like a vacuum leak. Get Ether (starting fluid) and spray it on the vacuum lines as the car runs...if the idle goes up or stabilizes then you found your leak.
