The problem- I"m having is poor idle, oil pressure seems to drop, and when I accelerate feels like i'm towing a big boat seems gutless. What could cause this.....is it possible MAF sensor...cause this? A couple of days ago I check codes and reading low voltage to MAF sensor.
I cleaned out with electrical contact spray, cleaned the iac with TB cleaner. I also adjusted the timing about 4 days ago as well. I think it's about 14 degrees, and i'm running 92 octane gas. Or could it be the timing that I adjusted or perhaps spark plug. Seems like it's surging when idling. Any feedback to help me narrow down this problem would be greatly appreciated.

Thanks.

 

Anyone????

 

ive seen that happen to a Passat once. it was sludge build up. its cause of humidity. hope thats not your case. i mean it was a passat, but it had the same symptoms

 

Well not sure if it's that, or maybe because of my synthetic oil....I didn't know when I bought car it had synthetic and I changed oil to conventional and after few years using that I put in synthetic oil this year. I just think with the timing thing I did cleaning MAF and IAC...seems kinda wierd now that all this is happening.

 

so...did you solve the MAF code? have you reset codes and checked to see if that one came back?

 

No i didn't...that is why I asked could that cause all the problems I'm having...poor idle terrible acceleration etc.

 

yup

 

So the MAF sensor can cause all the problems I'm having????? If that's the case I will just buy new one.
