I've changed a new MAF recently. ABS/PSM are keep coming on and off!
its driving me nuts!!

plz help!

thx

 

try to clean the TB.

 

Have you changed the F-hose and diverter valves yet? If not, that might be your cause at low rpms due to the vacuum leak.

 

lwf ???

 

I'm the same boat .. but I was getting MAF errors (PSM + ABS) rarely though ... would go away after I restarted that car ...

I did the CEC Electronics cleaner from Ace Hardware thang ... it went away ...

Its just starting to come back again ... I'm curious what it is as well.

Anybody?

 

I've had this happen to me. PSM/ABS/CEL flash...restarted the car....went away.

What was that?

 

Fouling of the MAFs. What airfilter are you using?

 

do you have a upgraded clutch....

 

I had this problem, and it turned out to be a split hose on the fuel pump. Showed up sort of randomly at idel, or turning a corner. No lights though.

Easy enough to remove the cover and sending unit to take a look for the split hose.

Sounds like a vacuum leak to me...

 

this could be anything from a vaccuum leak, to a bad replacement maf, to o2 sensors, to brake sensors, to plugs, to fuel line crack, to new fuel pump, to throttle body, dv leak, boost hose leak, to...

I think the best place to start if you are DIY is checking all the boost hoses. Mine was doing the same thing and I replaced my upper hoses with Agency power y-pipe, replaced the dv's with a 50/50 bov, replaced the exhaust with speedtech, replaced the lower boost hoses, and had EPL tune it. One of those fixed it!

 

Nola, you did use it as an excuse to mod.

 

Yes! All I needed to buy was a set of regular old boost hoses. hahah

My logic to my wife was "while I fix that, I may as well......."

 

Here is where it all usually happens... I zip tie the 3 vacuum hoses...

 

+1 - Vacuum/Boost leak.
