I have an annoying little problem with the idle since i changed the blue temp sensor,

Cold starts are faultless now but when its warm it idles at 900-1000rpm, i think thats a bit high for an M20 and when i switch it off and re-start (hot start) it will idle at about 700 untill i drive it then its back upto 1k.

more of an annoyance than a problem as it used to idle at about 700 once it was warm :mad:

any ideas are welcom

I dont know if it will help you on jetronic as mine is motronic but....

After testing the TPS it has no continuity at idle so it's time for a new 1 before the fuel costs get too much :mad:

dont know if this is the cause of the increased fuel consumption but it takes the micky doing 110 miles to £20 when it used to do 160 ish to the same amount :evil:
