Engine Mechanical problem
2002 Pontiac Montana 6 cyl All Wheel Drive Automatic
for a while I have been feeling jump or lag when I accelerate, only occasionally, only once in a while, but today, it started doing so about 1 hr into a trip home, when going uphill, to the point the van almost stopped. Also, it continued to do this sputtering nonsense for the remainder of the 15 minutes home. The other issue that doesn't seem related but who knows, is that the fuel gauge goes crazy when it gets below 3/8's of a tank first it goes to nearly full, then completely full, then when I turn it off, empty, than when I restart to where it should be then back to empty, needless to say I am filling up at half a tank constantly. Both of these problems did occur about the same time and about the same time that my A.C which I had just had checked died. We just had a the engine replaced after a mechanic convinced me that a head gasket blew. I am a 29 year old woman, with four kids, whose biggest feat is changing my own brake pads and thermostat, but I cant afford another repair from a shop. I have spent over 2,000 this month alone. Please any suggestions and or diagrams would be too helpful for words.
