Thanks for this information. My friend the service writer seems to think the same thing. I will in the next day or two take the overflow tank off and have a look around. I 've had some rodents under the hood last year and this year. They have pulled some of the installation down from under the hood and made a small nest I noticed this about 5 weeks ago when I put a new alternator on. About 4 weeks ago I had a new fuel pump installed by a shop that is a little bit closer to my home. I thought that I would give them a try but never again because after the install I started smelling gas and I could even see some on the side of the tank. Come to find out the seal at the top of the tank was leaking. I had a new seal/gasket installed last week where my friend works. I think that the shop that installed the pump should have recommended or included the gasket.
Could a bad vacuum line cause all of this? Also, If I bought a new ECM is it difficult to change the prom etc. inside that needs to be changed? Where could I have this done if I wanted some one else to do this? Thanks very much for your time
