Need 3800 help
Sorry guys its a Buick W but where better to get help with 3800'* than H body guys ? I posting this around a few sites.
91 Regal - L27 I believe. Wouldnt idle a month back but ran OK other wise so I took it to my "guy" and it was the MAF. He replaced it and it ran fine for 3- 4 weeks now.
Tonight - Im really pushing it comming home for running out of gas. Pull in and sit and wait for pumps, just idleing alls fine I get a pump, shut it off and fill up. When I leave it runs like ****, wont accelerate coughs and can hardly get any speed. Pull over unplug maf, still runs bad but will rev up so I limp home, but it runs OK once it gets settled into a speed and throttle position. I tried the old MAF back in and it runs just as bad not just the old idle problem it had but as bad as with the new MAF pluged in. I can drive it and get to work unpluged if it doesnt get worse, but I cant get anywhere with the MAF pluged in.
? = Do you think its the new MAF or is it another problem that the ECM can deal with if the MAF is unpluged ? Why it happened in conjuction with this very low tank Im not sure but I never did run out and it did start right up and leave the gas station fine but them would not accelerate. I did check for fuel pressure and I have pressure and the pump is pumping. What the PSI is I dont know but there is a fair amount of pressure, so I didnt plug up the fuel system or fry the pump which i originally figured, and remember it runs fair with the MAF unpluged.
