Re: 89 2.9l high hydrocarbons and rough high idle
I'm having the same problem, with my 88 of the same size. Plus I live in Washington, the emissions laws are pretty damn close to Cali's. I read somewhere that the 88 2.9 is particularly finicky about grounds. The poor guy ended up replacing just about every sensor he had just to find out a ground hadn't been reattached to the back of the block after a professional rebuild.
