cars jumpy

[95blackgt]

my 95 GT has recently gotten very jumpy when driving....its almost like its running out of gas and jumping forward and then losing its power but its constant....what could this be?

 

[Mrgreen94gt]

Sounds like a vacuum leak. Look for anything obvious in the engine bay, if that doesn't work, spray some carb cleaner or something around.

my car does that when the timing is advanced to far. It'll accelerate fine but at a low rpm cruise it'll jump

 

[95blackgt]

idk what it is, it comes and goes at time but when its there its constant, at almost all RPM's....nething else it could b...like a fuel filter clog or nething?

Mine does the same thing when I try to bump the timing up any at all. If I keep it at 8 deg. or less or run without the spout at 20 deg. it does fine. I know I'm leaving a lot of power on the table by running it this way, but I can't find the problem.

i havent changed my timing at all....it was fine one day and the next it was shuddery and jumpy ESPECIALLY in higher gears but sometimes in lower also

Mine acted that way once. I ended up replacing the TPS. Found a dead spot in the original TPS using a Digi Volt Meter.

mine does that but only when trying to pull up hill at low RPMs .. and i cant figure out what it is

 

[95blackgt]

could it be the fuel filter needing to b replaced?

Check your plug wires and make sure they are not melted anywhere and arcing off some metal.

 

[95blackgt]

no wires r melted and theres no metal touching...but its gotten worse....its like ur running out of gas, cars got NO pickup, NO ecceleration and its shuddering so bad it feels like the cars gonna fall apart at times...

Gotta be something with your fuel then, maybe. Your fuel filter is prob clogged. Have you ever changed it before and how many miles do you have?

 

[95blackgt]

i bought the car a couple months ago, it has 140,000 miles on it but ive put a few thou on myself and havent changed it yet

You should try and change it ASAP Cost a couple bucks.
