Were you too experiencing a hesitation at 2-3k rpm? I have the same thing currently with the 08 manual patriot...Bicero
I have a 2008 Pat 4x4 with 5 speed manual. It took the dealer 2 tries because no computer codes were being generated, but the mechanic hooked the scanner up to the computer port, drove the car and found codes were being generated just, for some reason, not written to the computer:
Bottom line: Throttle control unit (with sensor) replaced and the Pat runs fine.
Don't know if this is your problem, but worth looking into.
Jerkiness in the 25-30 mph range is not usually the transmission but rather the throttle control. Jerkiness in the dead stop up to about ten mph as you describe is usually the torque converter engaging it's clutches.Hmm.. have never felt this at 20 mph or so, but I have noticed that it's jerky from a dead stop up to about 10 or 15 mph if you hit the accelerator in a certain way. I've learned to gently take off from a dead stop and it doesn't do it. If I really need to burn off, like when merging from a stop sign, I just take the jerkiness.
Yes indeed ...on mi case i just change the spark plugs now is running great!!
Thank you.Spark plugs are the usual culprit. I believe the manual says to change them at 30,000, so you're double the recommended service miles. Plugs are a cheap and easy fix so you are wise to start there.
If the problem persists consider inconsistent tire wear. If like a lot of people you buy two tires at at time instead of all four, the difference between the axles may give the ECM some confusing data.
Don't wait too long. The last thing you need is a seized plug! Time can be as much a problem as miles.Thank you.
. . . I asked him when the next time to replace them and he said until you notice issues
How often have you had replace yours now that yours has 250,000 miles on it?
