I need HELP and Iam hoping someone out there can help.
Heres the problem.
The engine blew on my ride. I bought a new block(ie used) and rebuilt the engine. IT runs great for about 2 football fields but apparently once it warms up it wont do any better than idle. If I sit for awhile it will do the same thing.
Could it be a fuel flow problem? Or electrical? I need someones advice. Please help me I live in Michigan so I only get a few months of fun on weekends.PLEASE HELP ME B.Young You can EMail me at [email protected]
