Well, I hope it isn't my problem but I am getting P0135 which is the MAP circuit. I'm going to change the plugs and wires tomorrow as it's just about to hit 100K miles. I will check all my electrical plug connections and look for any leaks.
Well today I erased the code, and installed a dozen new NGK Iridium plugs and Bosch wires. While I had things apart, I checked all the vacuum and electrical connections I could get to, cleaned the throttle body and the K&N filters. Tightened up a few fasteners here and there as well as clamps. Had to remove/replace the belly pan to retrieve the sockets, etc. I dropped doing all this.
Cranked her up, and the idle speed had gone back up where it belongs and idling smoothly. Took a for a ride making a quick stop then quick start which was causing it to stall before. This time pulling hard and smooth with no jerking like before, and even broke the tires loose on a rolling start with no hesitation. Glad I don't have to deal with a MAP sensor replacement after hearing I would have to remove the supercharger for that! You'd think they could have used a little plumbing and found a more accessible place for it. Anyway, now 99,600 miles and counting.
Next on the list is replacing the turn signal/multi-function switch which has become intermittent.
