Answer 1

A friend of mine works at the plant that built the dodge omni. Several of the workers have omnis and other chrysler cars with that engine. They are rugged, reliable and not expensive to work on. I know of five cars with 150,000 miles on the original engine with little or no work done to them.

First, with the engine warm and running as best it can pull the spark plug wires off one at a time, listen to the engine before you put the wire back on. The engine will slow down and should miss worse than before. If all four cylinders make the same change it is a good sign all four cylinders are working equally. If one makes very little difference that is your problem. Either a leaking valve or head gasket.

If all four act the same try running a strong fuel cleaner through the system. I recommend the one from the dealer because it has NAPTHA in it. Do not spill on the paint. Put that in the tank and run it at least till it is down to 1/4 of a tank. That stuff is strong and will work well on either the carburetor or throttle body.

Next do a compression check to learn what it has for pressure.

After that if you still have trouble you will need to have a shop put a tester on it to determine if a sensor is malfunctioning.

Those little four cylinders are really quite amazing. A friend of mine hit something that knocked a hole in the oil filter. He didn't know he was losing oil pressure because the oil light was burned out. He got partway home and it started making horrible noises so he stopped and found that there was no oil on the dipstick. He added some he had in the trunk and drove it home where he replaced the filter and oil. that was 20,000 miles ago and he still drives it. It didn't ruin it to run it out of oil for that short distance! I don't recommend you try that but it still says a lot for that little engine.

My neighbor had one that went 180,000 miles before he sold it to a kid headed off to college. That kid managed to get 210,000 miles on it before he junked it. It had started to rust through the floor because it was in a couple fender benders that never got fixed. The engine still ran good!

I wish you luck with your 2.2 I am certain you will get several more years of use from it once you get the bugs out.

Answer 2

It could be the EGR valve. But before you replace anything else have the battery, and the alternator checked. Late model Dodges
have to have a clean 12 V to operate properly. I hope the other possibility isn't happening, the ECM might be at fault or the timing belt is not in time properly.

Answer 3

880,000 miles on one engine? If it's not a miss print then you have gotten your moneys worth.

The first guy pretty much said it all. The valve would be the guess. Other thing comes to mind is your distrubutor. The pick up coil inside could be causing it. Good Luck

Answer 4

Have some one check your timing belt. it may have stretched or it may have a cleat knocked off the belt. You may need to replace the belt. If the belt is completely shot, the car will not run. You have a lot of miles on that engine. I believe they recommend changing the belt every 60,000 t0 75,000 miles. I hope this is of some help to you.

Answer 5

Try some Sea Foam - check your local auto parts or marine supply store, runs about $6 to $7 bucks a can - it's great, works in oil or gas. May not fix the problem but it can't hurt.

Answer 6

sound like lost engine compression, take spark plug out one at the time check compression on each cylinder if compression not at specs probably your piston ring worn than it time to get a new car. some time your advance timing it not set right in the older car may need to set little higher than newer car.

Answer 7

I think it says "I'm gonna get a second date!!" At least that's the impression I get when a man shows up in a dodge. Year is of no importance to me. Unless you are going to buy me one for my birthday, in which case we need to talk.

Answer 8

if it was mine i would try checking the firing order it wires 1243.no.1 is marked om distributer cap then check the gap on the spark plugs bout any auto store will tell you the gap size.if not that id try oxygen sensors.but 880,000is alot of mile ive never seen a car go that long.but just a tiny hair of on timming will not run rite.so put the car on a machine n it will tell u wat the problem is,if none of that helps

Answer 9

Not worth putting another penny into. Crappiest engine I've ever seen. Don't think you will ever get it to run right again.

Answer 10

try a compression test to check valves (also rings) and also get timing chain or gears checked
