So I recently bought an 87 t2 with 132k km's on it and 6k km's on rebuild. The motor is stock with a ported wastegate. The car on start up idles up to 2k and rests at 1.5k rpms like it should. But as it warms up the rpms rise to 2k, and sometimes I start the car or go for a drive and the rpms will be at the 750 rpm mark where it should be, it has to be a blue moon to have it at 750 rpms. Whats the problem here guys?

 

Bump. This has to be sorted out, it's chugging more gas then it already should chug gas.

 

I think there is an idle thread in the archives.

 

I checked the archives and it was about a rough idle and pulsating idle. My idle is NOT let me repeat that NOOOOOOOT ROUGH and the idle is NOT pulsating.

The idle is usually around 1.5k rpms like it should and as it warms up goes up to 2k. I'm thinking it might be the TPS, but I need a for sure from someone before I go throwing away $100 on something I dont necessarily need.

 

I thought there was an end-all problems idle-related thread there.

Have you adjusted the TPS?
