Running issues

Link · 08-03-2012, 10:41 AM

Well today I went to do the head gasket and after removing the radiator and intake manifold. I noticed that the head gasket had in fact not been leaking and the crank case oil return was the source or half the leak, and the other half was when the previous owner replaced the intake gaskets he forgot to tighten all the bolts as most were finger tight. So new gaskets went in there, along with O rings and other necessary parts got replaced. Put it all back together.

Then when I test drove it the car still had the same problem were between 1800 and 3500 rpm's the car would stumble as if not fuel. I took a buddy for a ride who is very motor talented and explained it to my brother, diesel tech, and they both say that it must be the fuel pump, injectors, or possibly the Dinan chip is failing.

Thoughts?

you likely may still have a vaccum leak (or leaks)

Could be a bad spot in the AFM resistance trace.

Alright, so far she is doing good now. But we will continue to see what happens.
