Yesterday our truck started shaking at around 45mph, you feel it less when you exceed 55 mph. With that the exhaust sounds like it is straining and it makes fairly loud odd noise. It backfired once when my husband took me for a ride to show me the problem. The check engine light came on and he is going to try to go get the codes after work. He HAS to have his truck for work so we HAVE to keep it running.
I was reading different things online with people having similar problems. Some where saying change the O2 sensors, the spark plugs and wires, possibly catalytic converter.
I know once we have the codes we may have a better idea of the issues.
Also when he turns the overdrive off the shaking and the wah wah wah sound stopped.
Any help PLEASE!
have the same problem?
