NEW ISSUE HELP

my 95 riv is supercharged 3.8 I'm trying fix her kinks. When I go uphill between 45-50 mph she starts jerking I let off gas and stops and dosnt do this on flat straight aways any ideas maybe iac

Sounds like a bad plug or wire.

is this a joke? she's kinky and jerks you when you're on the gas? mine never does that to me!

well..be that as it may,in addition to checking the plug and wire I would check the conditionof the intank fuel filter.it might be allowing junk from the tank to get into and momentarily clog up. if you have a 95 and never changed the pump, I would say the filter most likely has a tear in it anyway being that old. mine was torn to shit.jus sayin

Just had fuel pump an filter replaced 6 weeks ago

For sure check the wires. Be sure to check the grounds also.

On the outside chance of a problem - check if your brakes (front and rear) are dragging adn check the condition of your transmission fluid.

WHAT'S GOOD AND BAD LOOK LIKE TRANSMISSION FLUID THANKS

Good fluid will be clear reddish color. Just open a container and you will see what the color should be, and what it should smell like. Bad fluid will be dark brown, and smell burned. If you rub some between your index finger and thumb, it may even be gritty. At that point though, you are usually looking at a rebuild.

It's a light reddish color kinda seems thin my friend agreed with me don't smell burned not gritty. I thought it looked a little watery don't know if possible. But I can run any speed fine on flat surface. Only on hills 40-55mph it shutters or jerks and I let off gas stops jerking. Give it more gas sometimesworks

to me it sounds like a bad torque converter.same symptoms coming from many trannys fixed by my cuz a trans specialist.i think.

What happens if you lay into it at 40 MPH on a level highway?

Level highway seems fine at 40 it has stuttered a little tonight between 55-60mph gave more gas and stopped

I'd test my fuel pressure and monitor it with a gauge while driving. If that was fine, I'd replace the plugs and wires.

I'm gonna work on it this weekend what do u guys think about maybe a bad coil I have replaced one about 6 months ago do Yall think maybe another bad one

Light reddish = burned a bit, most all transmission fluid is medium to dark red - if you get a small bottle of it (Dexron III or Dexron VI) and compare you'll see, hard to describe. Pale red, some would call it pink, is potentially a problem, and is a telltale sign of worn fluid.

That said I'll try asking this again - are your brakes dragging? If you answered before I'm sorry, I missed your answer.

To check you have to drive the car normal stop and go for several miles then put it on a lift, in neutral, fairly quickly - spin the front tire. There is a spec in the service manual for how much force should be needed (you have a service manual right?) and anything above that you should suspect dragging brakes.


Actually, you should strongly suspect dragging brakes if you get the car on that lift (again, in neutral) and turn a wheel, you may well be able to hear/feel the brakes drag.

The reason dragging brakes are important - if your brakes drag enough the electronic transmission thinks you are going uphill and unlocks the torque converter. Unlocked, the car speeds up somewhat, it relocks. And with brakes still dragging, the computer runs the unlock cycle again. Car speeds up a little, TC locks back up. This can repeat more than once a second if conditions are right. Point is that after whacking like this for a while, the TC clutch burns up and/or the TC will overheat and "grenade."

I'll check brakes this weekend I'm also going to change transmission fluid and filter and plugs and wires this weekend and will update anymore suggestions are welcomed

Also here is a list of things done recently, new fuel pump and filter, new CPU, new ignition control module, new crank sensor, things mechanic said I needed tune up, and valve cover gaskets. Got car cheap just trying to fix a few things. Can't tell you last time transmission fluid or plugs changed

Did you remove and inspect the plugs already?

If you are replacing the wires do not get cheap ones!!!

I plan on this weekend replacing wire and plugs to busy at work until then those back plugs look scary I mean impossible to get to LOL

There are good instructions elsewhere on this site for the plug replacement, use the 'search" function they are not hidden.

Fear not! With car in park, have someone push the car forward and set the parking brake with the motor tilted. Access through passenger side will allow you to reach back there and get all of them without having to go through the bottom of the car. Your hands may get scraped a little but way better than a 3 foot extension from underneath the car.
