It's possible that the engine internals are worn out causing the noise, probably the easiest way to check and verify this is with an oil pressure test with a manual gauge. A very common problem is when a vehicle jerks when accelerating. Well man, you can replace the solenoid if you want but it would be a lot better to rebuild the whole thing. Noises that change or go away after the automatic transmission shifts, mean we should stop driving and have the vehicle checked for problems. 1996 Mustang GT - sputtering,hesitating,shaking while accelerating: 1989 Stang 5. i have a 2012 gt 6sp manual with 3.

These are random jerks that will disappear at times. It makes noise when i accelerate, but even more noise when i take my foot off of the gas after the acceleration, but is usually quiet when the car is at a stop. When I put it in reverse it would not move. A very common problem is when a vehicle jerks when accelerating. It doesn't do it all the time, just every once in a while. 8 jumps and sputters randomly during acceleration and during almost every WOT upshift past about 4000 rpm. (Page 1 of 7). The clutch feels like it is slipping. But when it goes into 3rd it won't shift at 2000 it climbs to 2500 and jerks hard, if I let off the gas and let the rpms drop it dosent jerk as bad. So we're averaging one jerk or kick every 1,000 miles. Thunk/clunk noise and jerk when accelerating from stop Post by itshotinjt04 » Sun Nov 09, 2014 12:57 am I have noticed, in my 2005 Ford Freestyle SEL, that sometimes when I begin to drive after a stop, or when I shift my car from reverse to drive, there is a clunk type noise and slight jerk. In all cases, we were just cruising along smoothly, not acceleratg or deceleratg. i cant fully accelerate with out feeling like m car misses, funny thing is that some days its worse when other days it runs at top performance. I have a 2002 Toyota Camry and had no problems until last week.
