Wrench and Engine light still on
Need some help folks:
Two days ago my wrench and check engine light went on when i start the truck going home from work. It is stalling and seems to not have enough power. I disconnect the battery for 15 min and the engine light went off but came back up after few minutes. I decide to head home in limp mode (engine and wrench light both on.
Today i cleaned the TB which is very dirty with TB cleaner, changed the MAF sensor also since i broke the tab trying to pull it out for cleaning since the connector keep slipping out from MAF. Put it back together and both lights are gone but it came back when i start the truck again. Disconnect everything again for another cleaning (CRC electronic cleaner and MAF sensor cleaner) put them back again and fire it up...still both lights are on.
Off to store to buy a new TPS sensor, put it on...still have the same problem.
It takes me all day disassembling and putting them back together and running back and forth to auto parts and still having the same problem.
Do i need a new throttle body
or just take it to the dealer
which i'm trying to avoid since they quoted me $356 for a new one, that's why i'm trying to fix it myself.
Right now i'm down $129 MAF sensor. $86 TPS sensor, and all day trying to fix the truck.
I'm getting really dissapointed and running out of choice but to take it to dealership. Did someone ran into this kind of problem. I have 05 scab which has and issue and history of limp mode and wrench light for years now and i think it finally gave up.
Any advise on what are the next step to fix this will greatly appreciated. PCM reflash maybe since i have EDGE.
