I took most of the right(passenger) side of my engine appart this week to see if I could diagnose/fix a leaky exhaust (between downpipe and block).

After running out of time, I re-assembled everything and now the car starts fine, but won't idle at all on it's own. If I'm not pressing the gas, the car revs like normal, but if I let off the gas, it just spins down to 0 rpm and shuts off. It restarts fine.

I believe I have all the hoses reattached, and the only two wires I took off (that I recall) are the O2 sensor and airbox plug, both are also re-attached.

Can anybody point me in the right direction?

(1988 turbo 2)

 

check your turbo inlet duct mine did the exact same thing and the duct was cracked

 

The duct from the airbox to the turbo? Yeah, that thing is old and crispy and does have a rather large crack in it. I understand someone on this forum makes aluminum ones or something.

I will attempt to better apply a temporary fix.

 

That may have been the issue. I also found that the tube coming from the turbo to the engine was also not propertly tightened. Thanks.

 

Good job!
