I previously replaced the rubber intake boot at the throttle body.  I also carefully looked for any kind of cracks in the plastic tubing between the throttle body and the AFM and did not find any.

Today I did a basic compression test and the numbers were respectable:

Cylinder 1
Dry 165
Wet 175

Cylinder 2
Dry 175
Wet 185

Cylinder 3
Dry 180
Wet 190

Cylinder 4
Dry 178
Wet 188

I haven't had a chance to do a leak down test yet as I don't have the equipment to do it.  When I have some free time I will take it to my friends shop and do it there.




Those readings a good.  My gut says the leakdown test will not show a problem.

A hot start problem is usually an actual over-rich mixture.

Can the ECU get the wrong "data" (voltage) from the sensors report to it? ANSWER:  YES.

What are the voltage readings when you adjusted/checked the TPS?

Have you talked to Jim at 22RE Performance?
