A few weeks ago I cleaned my throttle body and IAC. Due to the gas mixer I took the TB off the manifiold to do the job. Ever since, the revs drop too low when coasting or braking to a stop, they drop to 400 rpm or less once the revs get down to 1000 or so, it's an auto BTW. On petrol the revs usually recover after stumbling a bit and it idles OK, but it stalls on LPG almost every time, consequently I have to remember to switch to petrol coming up to intersections etc. Have done ECU reset but no difference.
It seems almost as if the IAC is not opening quickly enough or is sticky. Is this possible, can I test it? What sort of life should I expect from an IAC? Mine has 320,000km up.
