Hey all, so I have an 03 ST170 (SVT for y'all americans) which had a bad idle. I cleaned the TB, MAF, O2 sensors and ICV. I also swapped out the coils, leads and spark plugs. also did the fuel filter.
It all helped a lot but when I slow right down and i put the clutch in the revs jump upto 2k for about 5 seconds before dropping to idle and I'm not sure why, its wierd and otherwise runs real well. If anyone has any idea what might cause it please let me know.
Cheers
