AboutLinda Expertise I have done a lot of work on older Mitsubishi's. Whatever has gone on with someone's car has I am sure happen to the one I work on. A lot of things, though might be the computer it could be a sensor too. Whatever I am not sure of, I will then hunt up the question useing the net. Don't know much about body work or painting a car.
Experience The Mitsubishi Eclipse I work on has over 167,000 miles on it. If it could go wrong it has. I have learned a lot from working on the car, reading books and asking people who work on other cars.
Organizations Church, I am a Christian.
Education/Credentials Have some college course on engines, working on them and keeping them repaired. Read a lot of books and try to stay ahead of things.
Question This is my son's car and ever since we had the engine rebuilt a year ago it has not been running right. We have been told that it has an exhaust leak, and that it need plugs and wires. We put new plugs and wires on tonight but it keeps back firing and still idle's rough and wants to die. This car has had the works, new slave cylinder,clutch,tires, wheels,new paint job etc. We are trying to get it running smooth so we can sell it before he goes back to school.
Answer Tammy: Why did you not take it back to the place that did the rebuilding and get them to fix the engine right. As my guess is that they did not do something right. But my repair manual says this first one was stark plugs, second wires and you said your did those. Bug also the distributor cap and rotor(did you do those too?). So then it says leaking EGR valve, air filter clogged, fuel pump not delivering enough fuel( that can be tested easily enough), timing belt or pulleys worn, camshaft lobes worn, but still if the engine was rebuild as it should have been those last two things should have been rebuilt. But on the backfiring.. emission control system not funcition properly(you should have this coded to see what the computer might kick out as to the problem with the car), ignition timing incorrect, fuel injection system in need of adjustment or worn excessively, vacuum leaks, damaged or worn lash adjusted and/or valves sticking... these ideas came out of my repair manual. But really I think you should take the car back to whoever did that rebuilt and see if they might find the problem with the car. As it could have been something they did not do right and only now is showing up in the car. God bless: Linda
