so my uncle has a 2002 E320 4M, he changed the CPS (3 times all bosch,1 looked different from the original so we bought 2 others that looked the same and still the same issue.we were able to return all of them but one ) it keeps stalling on him. it seems to stall when the car get to temp. any idea of where he should look next. on our reader (its a cheap ultra gauge it only shows the code PO335). once the car stalls it will just crank and just keep making noise like its trying to crank but it won't fully turn over.

let me know what other options.

Thank you!

I should ad he has a 2001 parts car, he also tried the CPS and a MAF from that car, fuel filter was changed last year. any other ideas would be greatly appreciated. He's 76 years old and just like to tinker on his own he's a retired mechanic from long ago but with primitive tools, this is the first time he been stumped with his car.
