MY MUSTANG IS HITCHING!?!?!?!? HELP
Hi guys. I just joined the forum. I have recently bought a 98 Mustang GT. It's a 5 speed standard. I have been having a very annoying issue with the car since I bought it. It is jerking/hitching when accelerating. Much more noticeble when under hard acceleration. If you put it to the floor it shudders quite violently. It shakes the whole car. It almost feels like if you were at a stop light and accidentally started in 3rd gear rather than 1st. Its that kind of feeling. I have changed spark plugs, fuel filter, rebuilt the rear end, and replaced the fuel pump today hoping that would fix it because the pressure was a bit low. Took it for a test drive and still hitching. WHAT IS THE PROBLEM? Could it be the standard trans going bad? Clutch? Please help. Thanks.

Yes, I had the coils tested and they were within spec. I checked the wires. I also had the car idling and had a spray bottle of water. Sprayed it on the wires. I saw no sparkling and the car didn't die. I did buy 1 new coil yesterday just to see. I tried it on both sides and the was no change. Very violent shaking, especially in 5th gear.

I took a good friend of mine for a ride lastnight and he suspects the clutch too. It feels like the jerking and kind of popping is coming from where engine and transmission connect. If you drive and soft easy and gradual the is hardly any jerking but when you step on it, it's bad. The rpms are not climbing nor is the speed. It's jerking too much to gain anything.

Any more thoughts? I hate to take the transmission out and have the clutch be fine. When stepping on it hard the gear shifter moves and vibrates a lot if that helps.

If there is a small garage by your area, you can take it to them and have them diagnose it, and then you can go and fix it yourself. I imagine the cost of a diagnoses wouldn't be too crazy.
Also, I don't know how much of a part it plays in with a 5-speed, but, my buddy used to have this old taurus with the 3.9, it sounds like it had a very similar issue, Hitching, and barely accelerating with the pedal matted. Turned out the transmission practically had no fluid, so if you havn't checked that yet it may be a good idea.
