Dodge problem?

Question

97 dodge avenger 2.5L V6 front wheel drive 4speed auto.

For a little while now i felt a really light jerk type feeling in the engine during light accleration, shruged it off for needing tune-up and plan to take care of it on my next day off. Well today my speedometer droped about 40 MPH then right back to normal. Then a little bit later in the day it's doing the same but also at the same time as that problem the car will jerk like it's trying to stop itself. I then hit a hill where i had to lightly accelrate to keep speed and the jerking i shurged off started again but pretty heavy this time along with the speedometer droping. And then ontop of that the radio kept shutting itself on and off. I have no clue what's going on anymore and if these are related anyone please give me a little advice i'd be very thankful.

I didn't add all this up til now when someone said they had the exact same problems and was fixed with some wires going into the battery line. But I did replace the battery and the post mounts about 2 weeks ago, it was coroded beyond anything i've ever seen before and woudn't let my car start even with jump. I also seen that the positvie cable melted a bit down a little bit from the battery so i skinned it cleaned the corosion out of the wires and taped it up. So with this being said I'm gonna guess because all this happen at the same I would guess that it's all related to electrical. Please read next detail for new questionnnn

O also forgot to add the trans was rebuilt at AAMCO 2-3 years ago.

What electrical things could cause the jerking. Before i take it for repairs i'm trying to weigh the idea of a new car/ verse fixing this one.

Answer 1

If you didn't have the electrical problems, I'd say it was the transmission.

Since you have electrical problems, it's more likely that there is a loose or bad connection between your battery and alternator. Your car is 10 years old, so, presumably, you've changed the battery at least once during that time. Since the industry standard is every 5 years, you might be due for a change! With any luck changing the battery will fix the loose cable connection. Of course, it could be the alternator, too, as well as a bad ground. Use a voltmeter with all the appliances running, to see if you get at least 15 volts; it is normal for the needle to oscillate a tiny bit back and forth. If it's below 15 volts, your alternator may need to be replaced, or, a wire is loose at that end. In some cars, low electrical output can confuse the computer.

BE VERY CAREFUL WHEN HANDLING CAR BATTERIES AND OTHER ELECTRICAL EQUIPMENT!!!

Good luck!

Answer 2

the engines are pretty plenty bullet data as long as you retorque the intake manifold each 5 or 6 years however the motor vehicle transmissions are rubbish. i've got been with the aid of 2 of them in a hundred and seventy,000 miles. confident I replaced the radiator & placed on an after industry oil cooler yet their nonetheless basically stable for 80 or ninety thousand miles.

Answer 3

With the radio going on and off I would think you have an electrical problem. Your voltage regulator may be hanging up on high. At first I thought you were having a transmission problem but maybe both.

Answer 4

Replace the Vehicle Speed Sensor (VSS) mounted on your transmission. It drives the speedometer electrically and affects transmission shifting

Answer 5

I think maybe also check the idle speed. sounds like its off. I dont think that that is the problem with radio though. for that could be a short in the wire. oh -maybe your alternator. that might cause both, or the car is possesed. lol

Answer 6

Back to "AAMCO" Transmission is Slipping Bad!!!

Answer 7

Do a full tune up and replace your fuel filter and trans filter...Then go from there! Sounds like you need to do your tune up!

Answer 8

clean battery cables and have bat tested at advance or other fine store...and tune it
