Throttle body test
 

Hey guys, i've been struggling with stalls at idle than wont start till cooled abit or push started.
I'm looking at the throttle body.
With the air box and tube set a side and clear view of the valve. When turning the key to on and press the fuel pedal. Should the valve be moving? It doesn't at all.

When running, my handheld is showing 15-about28% with idle to 9k rpm.
Shouldn't i have more?

It has nothing to do with the throttle body. Search for hot hard starting issues, it could be many things but the throttle bodies on these cars don't really fail.

Nope. Doesn't take much to spin an unloaded engine. Start looking in other places.

Hum. Will i have checked all vacuum lines, replace vacuum solenoid valve for the secondary air blower, battery, coils, plugs, wires, maf sensor, cleaned the starter out internal, gutted the bad cat, changed the front oil seal, had the alternator tested. Seafoamed about three different times, cleaned the throttle body, changed the oil, checked the fuel pressure, ect. Its been 6 monthes in. No i haven't checked compression. One other question. The vacuum line running to the front of the car passed the high power vacuum switch to the flap gate before the air filter has a check valve. It opens but holds vacuum to not shut again. Once heavy vacuum is made how would it return?

Could be compression related. It wouldn't normaly be my first guess, but you have thrown just about every other part at it, might be time to get compression checked.

Oh and air returns through the solenoid. The check valve should be on the engine side of the solenoid.

Did you ever do vacuum test on the engine with it warm? This is why proper diagnosis is needed.

oh the valve releases it. That makes sense. But i'll check it like i did the other three under the plastic intake. Because it still had strong vacuum on it after the engine died on idle going to the flap gate.

I haven't got it to a dealer yet because its over an hour away and i'll have to have a tow. I don't trust it out.

Tx for bumming me out on the throttle body idea :)
