Hey, I'm getting so sick of my car so please help out if you can.

The car in a cold start, starts really rough and then idles at 1500 untill it slowly warms up and idles down. Right after start up, if you press on the peddle it will bog down then rev up. What could cause this? I'm so sick of my car running like ****.

 

checked your temp senders?

 

Its a 79 so i dont think it has the CHTS.

 

Air regulator, timing, mis-adjusted idle screw, vacuum leak on the intake manifold or major vac lines, AFM....

 

that sounds like almost perfect z cold start to me, if only mine would be that smooth. maybe cause a took out all my cold start stuff.

 

Hm, that sounds almost exactly what's going on with mine ever since I did the Z31T ECU/MAF conversion. Doesn't happen all the time to me though, but mainly when it's a cold start.

In my case, if it is a vacuum leak, I haven't seen anything out of place.

 

i have found my z31 turbos liked to warm up for a few minutes before takeoff---the NA only wanted her oil prwessure to come up before going anywhere....
