after trying all the things various 300 club members suggested / i believe the vacuum pressure is low but it is working (i put a guage on it). on the gauge i used, it had a reading that said: the pressure was 1/2 of normal; possible problems... late valve timing or check for leak on intake manifold or heat riser. so first i looked for a vacuum leak and found one of the intake manifold bolts was loose...and that helped a bit...and the rough idle improved. i also cleaned the check valve on the reservoir tank. the brake pedal goes down easier now...not being so firm. so there is progress. thanks to all who submitted info / i will report any more successes. billlllll in hot hot hot kennewick washington / it has to be over 100 today ------------------------------------ To send a message to this group, send an email to: Chrysler300@xxxxxxxxxxxxxxx For list server instructions, go to http://www.chrysler300club.com/yahoolist/inst.htm For archives go to http://www.forwardlook.net/300-archive/Yahoo!
