I take back my "recently" statement. And I know for a fact they lessened my idle before. I could feel it without a doubt. I was having the hard shifting out of park. They sprayed my MAF and cleaned a few other parts. I just got back from the shop where they let me go in the bay and check out the repair in progress. Also showed me the new pump with new filters. I didn't realize how clean my frame was until today. Some of it is still black, which is odd because I need to replace my rockers due to rust. Its taking them a little bit longer because some of the bolts were not re-usable. He had to make some bolts to fit. I have confidence in these guys, plus not that it matters, but they have extremely high 'AAA' reviews and ratings. My mind might have misinterpreted some of the things he was explaining to me, cause all I could think at the time yesterday was "$700!!!!!!????" LOL! so maybe I heard his idle thing incorrectly. ANYHOOOOO...... :P
