I have a 2001 v6 manual. When I'm in 2nd-5th gear, if I am at 1700-2000 RPMS, my car studders a bit in the acceleration and I feel like the stick is shaking really weird. This problem never occurred when I bought it and I have ran it 15,000 miles in the 11 months and it's around 96,000 miles on it now. I do my oil change personally every 3k miles and this time I put synthetic oil.

I checked the air filter and it is a bit nasty and I am waiting on the CAI to be back in stock on americanmuscle.com so I am guessing it could be the air filter possibly. I was thinking if I could take the air filter out on a test run and see if it would work smooth but I don't want any chance of anything going into my engine.

 

could be the filter, mass air flow, or it could be your tps, or it could be your plugs

 

had the same thing happen, cleand the filter, maf, tps, and it turned out to be my plugs. Swapped them out w/ some autolites NO BOSCH and changed my whole car it seemed :P. Cuz it was doing the same thing yours was

 

AF, fuel filter, plugs, wires, coil, MAF, TPS

 

DFPE sensor going out maybe?

 

I had the same thing happen. I also have v6 3.8L Manuel 2001 Mustang. I had a tune up done which didn't fix the problem. Took my car to the ford dealership.

These are the notes on the invoice: vehicle jerks on deacceleration and acceleration above 35 mph. coil faulty. EEC TEST.DCL TEST. FUEL System TEST and IGNITION SYSTEM TEST. Found the coil faulty replaced and retested==PASSPASSPASS

PART:COIL ASY IGN unit price 148.85

it cost me about 300 to fix. I can take a picture of the part that you need to replace. Let me know if you need it.

I have not had any problems since i got it fixed.

 

it cost you 300 bucks to get a ~100 dollar coil replaced....

 

The 300 maybe an over estimation. I took my car to the dealership labor cost is always is high. My bill came out to 450 but I also had other maintenance stuff done.

 

good lord thats crazy

 

yes i would like a picture of the coil. hope this is not so serious as it's been going on for a few weeks.
