Hi all,
Now a long time since my last post.
I’ve been running onto an apparent rich condition for a while, and now I’m trying to get to the bottom of the problem.
To start there are no Trouble Codes
Nice and clean injectors
Good pressure regulator
Fuel pressure at 39 psi.
Right now doing MAF sensor test and O2 sensors to be done.
MAF sensor test completed and there is what I consider a high voltage output at idle (1.2 volts)
The Chilton’s book call for 0.6 volts at idle.
Is my MAF voltage out of range?
If I start her from stone cold there is some hesitation and takes one to two minutes for the idle to stabilize. And if take off quickly after that and and give a medium/high
acceleration, I heard and feel some popping in the exhaust pipe and starts bucking so have to ease on the throttle. Also some raw gas smell (Have to mention that the smog system and the secondary cats are not there anymore)
Like I say, I will test the O2 sensor voltage at the PCM harness, but does anyone tell me what is going on with my MAF? The voltage increases to over 3 volts... And I go thru a full fuel tank amazingly quick ☹
NO ERROR CODES
Any ideas? Thank you all!!!
