Dodge Omni Car Repair Questions and Answers

Question: 1990 Dodge Omni mileage: 142,000. Engine runs wonderfully, and get awesome gas mileage (35-40 mpg), however, when accelerating, the car will gag for a few seconds, then suddenly take off very fast, all the while my foot is holding the gas in the same position. There are no clutch problems, then engine was rebuilt, and the trans replaced about 20,000 miles ago. I've replaced the cap, wires, rotor, fuel filter, plugs, air filter, etc.

Answer: Check the fuel pump pressure and the fuel pressure regulator. Also, check for vacuum leaks and check the operation of the EGR valve.

Question: 1989 Dodge Omni mileage: 150,000 miles I have this problem: This Omni is driving crazy, I had it in the garage many times and no one can find the problem. It has a miss...if I gave lots of gas its fine...if it idles its fine...but if I try to go a steady speed, that’s when it misses, like sputters...backfire sort of thing. I have changed the computer, coil, spark plugs & wires. I tried with 2 new injectors going all around, and last I have changed the intake manifold gaskets. I also had the fuel pump checked...its ok

Answer: We have seen similar problems that were cured by replacing the O² sensors.

Question: 1990 Dodge Omni mileage: 104,500. Recently I noticed squealing front disc brakes they only squeal with my foot off pedal & if I press brake pedal about a 1/2 in the squeal disappears. I have brakes & they work fine but there is something wrong - squealing is super loud on the freeway & embarrassing to drive. Sometimes, rarely, it will go away for a few seconds though. What is going on & how do I fix the problem.

Answer: Replacing the front brake pads should fix your problem.
