Just today I removed my acv, egr, and split air with blockoff plates from 2751 engineering. I used plenty of gasket maker for both the egr and split air, but the gasket for acv was still in perfect condition, so I left it alone. I then capped the 3 vac lines for the acv and the 1 line for the egr. I also at the same time removed my air pump. After the removal of these, the car will no longer idle. It starts up fine and runs well enough until it dies. The only way I can keep it alive is by to continuously giving it gas. I had to limp it home in this manner and during the drive it ran pretty much perfectly, except that I had to keep giving it gas to keep it running. The car is an 87 turbo 2, and I still have both cats on the car, as my racing beat exhaust should be coming in within a week or so.

Thanks!

 

Bump. I've searched and searched and can't seem to find anything similar enough to my problem to help. Thanks in advance!

 

sounds like vac leak to me

 

you're probably going to need to set the idle using the idle stop screw and set the TPS.

 

I was leaning towards a vac leak as my problem, but can't think of where one would be. I'll probably use a whole bunch of gasket maker on the acv blockoff plate and hope for the best. Also, prior to doing this, my idle was perfect. Would removing these things make me need to reset my tps or change my idle screw?

 

Use proper new gaskets all round instead of sealant. They're very cheap from Mazda or you can cut them from gasket paper.
