so maf , orig, dead, is 15mpg (limp mode)
and china maf it 10mpg (insufferable, despicable, maf)
no sign, is fast post.
id try to find a used, good maf.
what is happening , is you start car, and it goes so rich , the ECU can not correct, this, in fact it believes the high maf reading and just injects like mad.
gorkys, had a sweet spot, that a certain throttle angle , allowed the fuel mix to almost hit good, in fact it ,would go closed loop for an instant ..
later here:
i looked at it and saw the hot wire was dead. almost zero current. 10x less than normal, and then saw the wiring error.
it seems your MAF is worse. (assuming not 2 failures. like high fuel pressure)
The guy at motormagzine.com Mr. warn, one time, used a pot and 5vdc supply and built a MAF simulator, his sidekick buddy, became a human MAF.
he drove and buddy , turned the knob , to simulate a good mAF, and saw the car ran perfect. He did this so he did not charge the customer $500 for 1 part
turned out the maf was bad. One of their best published verticals. (same trick works for MAPs too)
there are only 2 ways to fool the ECU (3 with failsafe)
1: add air to match the lie (maf lies)
2: simulate the maf.
good luck to you,
quick reply
this part is what replaces the Venturi and main jet in a carb.
imagine someone drilled the carb main jet out 100% or more. like the jet, this device must be accurate.
but the jet costs $5 and the maf $230 rebuilt.
