Electrical problem
1998 Chevy Monte Carlo 6 cyl Front Wheel Drive Automatic 120000 miles
----------------------------------------------------------------
I have been trying to find out the problem with the car for the last month or so. The car runs great when it wants to run.The car will start but no longer than 10 to 15 seconds and then it just stalls and dies and a choking noise can be heard from the front of the car sometimes. The RPM's jump from 1000 down to 500 or so and thats when the car dies. I took it to a shop and the said it was the fuel pump which i kinda of thought but i wanted to get another opinion before i spen close to 800 bucks for the repair any ideas let me know PLEASE!!!!

it could be did they tell you what pressures you had and any trouble codes

Well I have a scanner and the only codes that I got were random misfires, and bank 1 too lean. I had the spark plugs and wires changed and cleared the codes and no check engine or service light came on. When the car does stay running when you put the car in reverse there is a loud knocking noise coming from under the rear of the car.Also when giving the car gas it sputters and stalls out.

have you checked you fuel pressure.

What are the codes? P0171? I was getting this code for a long time, over 4 months probably. I Had a similar problem to yours. I don't like taking my car in when I can repair it myself but it wouldn't start on me once. They ended up replacing the Mass Air Flow (MAF) sensor. It seemed to help but it still didn't run the best. Took it back, they said the O2 sensor was working intermittently. I replaced that myself and now the car runs fine. The problem with replacing the MAF is that costs almost $200. Good luck and I hope this helped
