hi
my car is floodin i mean its getting to much fuel.
its 350 iroc. maf i good for sure,because i`ve got couple of them and tried on each other. I think its maf related.
maybe power relay. what do you think?
its getting tooo much air flow readings.
what should be the voltages on abcde wires from MAF sensor?
what else could it be. tommorow i`ll check tps voltage and adjust it if neccesary but could it be it?
what have the most meanign in mixture beside maf?
thanks

 

I think you're looking at the problem wrong by picking a sensor and going from there.


Start by elimination, where im going to start is does it flood both cold and warm? For example if it never does it cold, but does do it warm, I'd be fairly confident in saying its your 02 sensor.

When does/doesn't the problem happen?

 

get a fuel pressure guage, and check the fuel pressure. see if its dropping off, then pinch the return line and feed line (after you get pressure of course) and see if its bleeding off. If your pressure drops with the lines pinched... you might have a bad injector (or more) that is flooding your engine. If your pressure holds... release the return, and see if maybe your Fuel pressure reg is letting the fuel into the plenium or something. If the pressure holds, your ok with this and can move on to something else.

update in problem:

it starts good,good idle , after a short while idle drops to ~510 rpm.

when hiiting accelerator fast it stalls before reving up.

when hiiting accelerator slowly it revs up good.

what is it?

fuel pressure?
it was checked 2-3 motnhs ago.
i have afpr.

what it should be?

maybe some vacum lines leak? and fuel pressure cant be increased fast anought???

any ideas?

no code.
