Hey all. New to forum. I have used it before but havent registered til now. Used it to help me replace a water pump on my Jimmy. Now I have a question. I have searched and found several issues on the erg valve and cpi unit. While driving I will notice on my tach that it will decrease 100 - 200 rpms almost all the time. I think this might be the cpi(spider) unit losing pressure. I would like some feed back on that. Also, the erg valve is constantly becoming stopped up. I bought the vehicle off my father about a yr ago. Yesterday he told me he had it at the dealiership earlier and found that the erg valve has a recall on it. Does anybody know anything about this recall?

Thanks,
Auk

There is a TSB for the EGR, not a recall. Here is the TSB: (This isn't a free service, the dealer will charge you)
