NEED HELP- 3 CEL codes!!!!
--------------------------------------------------------------------------------
39k milew on car, about a month ago i started having problems. car start up and runs fine when cold. but when u run into store for 5 minutew and come out and try to start up , car cranks a long time to start up , runsrough, and can not go over 3.5k rpm. let it cool down and all is well went to autozone and obdii meter said bad cps, so i repace it with help of Glyn Ruck-THANK YOU and it was a challenging repacement. problem not resolved!!! go back to autozone and get these codes P0335 P0101 P0172 i clean maf w maf cleaner and put dielectric grease on connector, also did this w cps connector. same problem i must admit that i did break off by accident a few months ago 1 of the 2 plastic flanges on the maf body that secure the maf to the engine. it still seems attached well w just 1 flange connector. whas the problem, could it be from the dielectric grease??? could it be cause of having only 1 of 2 maf flange connectors??? if so, can i buy just the plastic maf body and use my current maf sensor??? thanx, mike

update, cleaned maf . cleaned connectors to maf and cps with contact cleaner. went for a drive and car ran great for 10 minutes and then acted up again-- long crank to start, runs ruff, and cant rev over 3500 rpm. only happens when car is hot and usually on restart, forgot to mention sometimes get message on dash " ESP malfunction, go to work shop" and " speedtronic not funtioning proceed to work shop" this is verrrrrry frustrating. the temp gauge in dash appears to function normally, slowly climbing to 85 degrees when fully warmed up. glyn had mentioned testing the temp sensor, hey im up for anything at this point, where is it and how do i test it??? many thanx, mike
would someone from Tech Talk please chime in, im very discouraged, thanx, mike

300E a couple 1994 w124wagon E320 Wagon/,1971MGB Track/Rally, MG Midget Autocross ,2000 E320 wagon.
The maf
is dead. No manner of cleaning is going to fix it.
You do not need any dielectric grease in the connectors of either the cps or the maf.
Where did you purchase the new cps from? if autozone,take it back it will never work as intended www.autohausaz.com has the real deal.
Besides the bad maf a broken flange allowing even the tiniest bit of unregistered air into the intake will cause some of the problems you have.
The other issues most likely need a good diagnostic scan at a shop with an SDS. either indie shop or dealer.

thank you very much, miike please explain to me why the problem only occurs when engine at full operating conditions?? glyn mentioned temp sensor could be faulty?? on a budget due to large medical bilss from ill family member. bought cps off Amazon, Standard Motor Products Brand. should i try to replace parts sequentially to see to save $, where is most economical place to purchase relable maf?? What brand is acceptable? Rock auto and parts geek have good prices. thank you so much, mike
