2004 Malibu engine dies then restarts, RPM fluctuates
Hi, we bought a used 2004 Chevy Malibu<ST1
</ST1 that had <?xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com
</st1:metricconverter>71,000 miles and had it 2 days before my 16 yr old daughter cracked the oil pan and drove it until it locked up. We bought a manufactured rebuilt 4 cyl. 2.2 ecotec engine same size that the car had from another Chevy Malibu<ST1</ST1 that had 65,000 original miles on it. Once installed the car would run ok for a while then it would die every so often like at a stop light or when you are parking. We took to 2 different Chevy dealers and nobody could figure out what was wrong because no codes where being thrown. So we had the fuel pump replaced with a new one and had a new fuel relay switch put in and it ran ok for approximately 6 months but then started to die again. The car always starts back up after it dies. The other day when we replaced the relay switch again, my husband could not even touch the relay switch to change it because it was so hot. The rpm gauges also fluctuates when this is happening. Yesterday when my daughter was driving the car she said it was like she was giving it gas but that the car was not getting any gas then it would all the sudden surge like it got gas again. The car will run ok sometimes with just RPM fluctuating, then it will start dying every time she drives, then run ok again. This has been going on for 11 months now and nobody can figure this out even after new fuel pump and relays. We have been told maybe there is a short in the wires to fuel pump from relay, maybe electronic injector is clogged up, to they have no idea just live with it. Please any help you could give would be greatly appreciated. Do not want her to be in bad wreck because car keeps dying. Thanks.
