92 300te. Stalls when hot wont restart for days.
Hi everyone. New member and very experienced Tech with the new stuff. NOT the old stuff lol. My recent purchase has me stumped. It runs good at high rpm and when its cold. Once warm it misses off idle eventually if you dont keep the revs up it dies and will not restart for literally days. New crank sensor, new plugs, new OVP, New wires and i swapped the cap and rotor from my 190e that runs fine and it misses still. Fuel pumps come on at ignition and i jumped the MAS when it was not starting to hotwire the fuel pumps. Still a no start. The headgasket is leaking externally but no mixing. I aquired the car from a customer at work. It was towed in and nothing would get it to start even though it had spark and i sprayed starting fluid. Did a compression test with 3 differnt testers all low compression 110 120ish. Told the cust it needed an engine. He didnt wanna spend the $ so i made an offer. I bought it thinking it needed an engine. But low and behold few days after i bought it the thing started right up and ran perfect. I drove it about 30 miles 28 of which were highway. Get off the highway and it stalls at the light. Towed home. New bremi coil as well. The previous owner replace the fuel distributor i think because its clean as all hell i could eat off it. The actuator below is old though. Please help. This car is driving me insane. When its not starting the plugs dont look fouled. I think its a fuel issue but everything seems to work.

Out Of Control!!
Post the name of your shop---I am sure that most would be very interested to learn about your diagnostic techniques---"I think its a fuel issue but everything seems to work"---wada folks do drive by the shop--you look out the window and then you tell them whats wrong with the car.
