p0174 is for the mafI have misfire on cylinder 1 2 5 6 7 and 8. With codes PO174 PO316 PO300
Well it also had a running lean code too. But ya im gonna give that a try too. Thanksp0174 is for the maf
p0316 misfire during first 1000 revolutions
p0300 random/multiple misfire
looking at the codes i'd say either the maf is dirty beyond belief or busted. check the maf wire and clean it first...remember to only clean it using a proper can of maf cleaner which is sensor safe
Ya I'm going to throw it on the charger overnight and try it again in the morning. I can see what your saying about the other codes being thrown because of the MAF. But isn't there a complete separate one for just the MAF itself?.. Or do those codes just double for the MAF too?..1slosix said:charge up the battery then try to fire it up...and you are throwing a maf code
Do you have a tune?Stalls, sputters, really rough idle. One of the codes that popped said Running Lean.
Yes but it's the same tune that's been in it for the past 5 years.Do you have a tune?
I had similar probs
(Idle up and down between 1.5k - 200 rpm
Would shut off when idling etc was running lean)
Took of the tune and runs better then the horrible tune previous owner gave me
Ok so now an update. After cleaning the MAF yesterday and charging the battery all night, my car will crank but will not start.I had the p0174 & p0171 codes anf all it turned out to be was a bad coupler behind the maf. It was letting extra unfiltered air into the engine. Only a 10 doller part from advanced.
Seems like the MAF would not keep it from starting. Seems like that would just be rough idles, poor running, etc. You might be right about the fuel filter. It could be clogged enough to effect your fuel pressure. I think there is a shrader valve on the fuel rail where you can check the fuel pressure. You should be able to borrow a fuel pressure check setup at your local auto parts store. Are you getting any new codes now that its turning over, but not starting?Ok like I said, it will now crank but not start. I kinda thinking fuel filter maybe?.. Also does anyone know if the MAF would cause these problems too?..
