As the title states I had some issues going on and I fixed them and now I'm getting a P0507 code popping up and after I cleaned the TB and maf it went a way for a little bit then came back so I searched on the forums and saw that I need to clean the MAP so I did and it ran great until the code came back. After I reset it the car runs great until it comes back. I have a canned tune from PCMforLess and have always had their tune and never had problems. Mods are 60#s, 3" cai, 2.8 pulley, cobalt addiction heat exchanger, maddab header/ zzp downpipe combo. Could this be a tune issue? Or do I need to start replacing sensors (Maf, map, IACV)?

 

Possible causes
- Dirty throttle body (You just cleaned it)
- Electric throttle control actuator misadjusted or damaged
- Faulty Electric throttle control actuator
- Intake air leak
- Poor electrical connection to the Intake Air Control (IAC) valve

When you cleaned the TB did you spray fluid into it or did you soak a rag and clean it that way?

 

When I cleaned it I took it out of the car and sprayed it to clean it

 

At this point I'm thinking it's the tune. I'm sending my PCM to zzp tomorrow and hopefully can expect it back next week. I hope that solves it because nothing else seems to be the problem

 

If you cleaned it and are now throwing a p0507 then it's more then likely the tb is messed up.

 

i was throwing the p0507 code before as well and would clear it and it would go away for a little bit then come back. I hope its not the throttle body but if so then Ill have to get a new one soon.

Also I think I had a vacuum leak the hoses were dry rotted and when I tried to even take them off they ripped so I just replaced them. When I get my ECU back I will be able to know more of whats going on.
