Delayed Start for M20 Problem (Master Tech needs help)

[funcrew]

I had the same problem, the coolant temp sensor cured it. Colds starts were fine for me but warm and hot starts were a problem. Obviously, if the computer thinks it is cold, it is going to "choke" the mixture. My car has been starting instantly since the swap.

I also checked and tested the AFM, TPS, replaced the valve cover hose, replaced a leaking hose that went to the charcoal canister, and made sure all intake manifold fittings were tight. Also, I had the throttle body off and cleaned the inside.

Anybody have the P/N for m20b25 coolant temp sensor? Where is it mounted?

The sensor is mounted just forward of the #1 fuel injector. It's the "lower"bone that's a pain in the ass to get to, I use a universal and a deep socket.
