Asked by Dec 12, 2015 at 01:58 PM about the 1992 Toyota MR2 T-bar

Question type: Maintenance & Repair

I've  replaced coolant temp sensor, plugs,
wires, coil..no help.  Cleaned the idle
sensor and that helped the warm idle at
first but started stalling now again when
warm.  What should I try
next...Distributor? ?

If you cleaned the idle sensor (IAC?) and it helped for a while then maybe you need to replace it.

Yes that did help it keep idling. So I will do that but when I did shut it off after almost an hour it would not restart until cold again.

Check fuel pressure at the rail, Idle air bypass wont create a NO start typically. 5S-FE engine right?
