Alright, my car is once again idling like crap. the rpm's are fluxuating between 800 and 1200 and the oil pressure gague moves from around 1/8 to 1/2. I am positive that it is a vacuum leak some where. I did replace the belts and they did squeal but I tightened them up so thats not the problem. I am thinking that the whistling may be the air flow sensor plate. Does that sound right to anyone? Good news is that I changed my oil the other day and didn't see any signs of a broken head gasket. I also was able to back her out of the garage; so no probs with the transmission so far. Here is a list of all the things I have replaced so far inorder to better diagnose my problem. clutch master cylinder fuel pump fuel filter fuel distributor cap and rotor spark plugs, wires, coil replaced seals for entire upper engine (minus elec. distributor and valve covers) new hoses for water pump new vacuum line hoses. (not original thickness temps. from the auto store) vacuum switch Jason 2256 To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
