I just wanted to get some fresh ideas. I am still trying to figure out this car's surging at cruising under 45 mph. I have gone thru all the setting and everything is reading as it should. IAC is 26 at hot idle and tps is .42. TPS is brand new and IAC is functioning as it should according to my scan tool(snap on modis).
I just went out and tried to eliminate the coil pack. I ohmed all the towers and they all read 11.1k. I warmed the car up and put it in drive and held the brake tight. I ran it up against the brake to see if the coil pack would start breaking down but it was totally smooth no hiccups. I put my hand at the tailpipe and the air coming out was smooth as could be.
This all makes me lean towards the TC lock up solenoid. Is it possible that it could get stuck half way? Once over 45 and the TC locks completely it runs nice and smooth. From a stop, give it a bit of pedal it runs fine. It is when I try to take off normally or I am cruising under 45 that you can feel it. It really baffles me. I have tried even dropping the tranny into 1 and shifting it myself and it still shows the same symptoms.
Any ideas are greatly appreciated.
