Question about 1989 Dodge Dynasty

1 Answer

Loosing power at cruising speed

I own a 1991 Dodge Dynasty with the 3.3 litre engine. Car starts fine and runs fine until I get out on the freeway. Sometimes within about 15 minutes or up to a half hour of driving the car looses power. As I push the gas pedal down the car sputters. I let my foot off the gas and the engine smoothes out but I'm forced to pull over. Car never completely dies. I sit for a minute car regains its power and off I go. Problem will repeat down the road after awhile. Doesn't seem to be a problem at slower speeds on back roads. fuel starvation issue?

Hi. I have two Dynasty LE cars, (a 91 and a 93). Both have the 3.3 litre. The 1991 had almost the same problem as yours except it would only do it once the engine warmed up, (similar to your freeway issue, given distance and time for the engine to warm up to operating temp.) I had it in about three shops before the dealer found an intermittent fault with the cam and crank sensors. I replaced them and now it runs just fine. I hope this helps.

No maintenance done in 3 years. Car starts but does not remain running fuel filter or plugs or both?

do a computer self test.

Insert key into ignition. turn as follows;

off-on, off-on, off-on. " on " is when the dash lights come on and "off" is one click back from on.

Codes with flash out on the check engine light is pairs of numbers; 5-5 being the end of the test.

Google your findings; eg, "1991 dodge dynasty code 22"

Your condition is usually a sign of a bad crank or cam position sensor ( if you cant keep the engine running by pressing on the gas pedal.)

If you can keep the car running by pressing the gas pedal than your problem is the idle control valve or a broken vacuum hose. has a tutorial on these parts.

1991 Dodge Dynasty LE car will suddenly die while driving. If I pull off the road, turn the ignition off and restart it- will start but when I put it back in gear the engine stalls again. After five or ten...

Sounds like you are having a fuel problem with the fuel filter. If you have not had your car serviced in quite awhile i would do so. At least change the fuel filter and check the air filter as well. Hope thias will help you.

Won't shift out of 1st gear

You need to have the transmission computer scanned for codes. It is likely in limp mode because it has a bad speed sensor.

Fuel pressure drops immediately to zero when engine is shut off.

I am not really familiar with the setup there but I'd be looking for a second relay to kick the pump on when cranking.
