when you press the gas peddle the truck just woln't go sometimes. It's almost like there is a sweet spot and you have to get into that spot to accelerate. Turning tha AC on makes it 10 times worse.
A Little History:
I bought the burban used almost 3 years ago. we had the dealership change the fuel pump (after trying 2 pumps from advanced that didn't work). Incidentally, the gas gauge hasn't worked since, but I just use my trip odometer to keep from running out, so NBD. We have also had to change the water pump, clutch fan, belt, tensioner pully, ac compressor (only the pully was bad but we knew the compressor had a tiny leak according to the mechanic that serviced the ac the summer before). All pretty normal stuff I'd think in the course of 3 years for a truck that now has 200k miles on it.
Recent History:
Back in Aug on a trip from Myrtle Beach SC to Augusta GA we started having prefomance problems. Before that the burban took the hills between Columbia and Augusta like a champ, no downshifting, no loss of speed, with or without either AC or CC. The truck started lugging down in the hills. We were losing sometimes 20 mph. Definitly something wrong. We took it to Advanced Auto and thier code showed a multiple misfire something. My husband changed the distributer cap and rotar button (we had installed new plugs only a month before). Same problem on the way home, no power. We took it to the dealership and they said it needed a catalytic convertor, new plugs and wires, and a fuel injection cleaning. I let that sleeping dog lie, because I didn't and still don't have the money for all of that work. My husband changed the spark plug wires and we left it at that for a while.
Three weeks ago we made another trip to GA and it lugged down to about 30mph so my husband pulled over, totally frustrated. I had him disconect the battery for a few minits when we reconnected the SES light went out and we were able to get down there and back, I drove, without it lugging down that badly agian.
Two weeks ago knowing we had to go to GA agian (his family lives there and we visit often) I had the catalytic convertors cut off and straigt pipes put in. From disconnecting the battery the codes were lost and we didn't know if only one convertor was bad or both. now the SES light burns all the time. I drove us down and back without too much trouble until we got into town traffic. I was attempting to turn left back onto the highway and when I hit the gas the truck just died. It started right back up and we made it home but we still don't know what the problem really is. The only codes it is throwing now are catalytic converter and O² sensor.
On a side note, I had a 6 cylinder ford that suffered from that sweet spot syndrom too. It was totaled trying to turn left. I sold it to the junk yard and they put it back together but still couldn't get it to accelerate until by trial and error they replaced the harmonic balancer. It runs great now.
Now I don't have a lot of money to spend looking for the root of the problem. I need opinions on what the core problem is. The burban drives around town just fine for me. But we need it to be able to make trips too. My husband will not drive it anymore, he thinks the truck doesn't like him. I say it doesn't do it to me because I have experience with vehicles that don't go like they should. To some degree my dodge has this problem too. Mayby it is me:neutral:
Sorry this is so long
Thank You in Advance
