Question about 1994 Volkswagen Jetta

Jetta hesitation/shaking during acceleration

I have a 1994 VW Jetta 2.0ltr manual trans. Recently put in new or slightly used transmisson to replace old one which went out. Car over all has been great to me. This is my second Jetta I have owned.

My car has been shaking or hesitating when I press the gas. It does it in just about every gear and I would say maybe more so when its warmed up. It also has been dying after Its warmed up and I stop at a store and start it again. Takes several attempts to get it to start.

We have researched this everywhere and found so many possible issues it may be. We so far have replaced the cap and master air flow censor. We also found a cracked pipe which we jimmy rigged to work until the part comes by mail. 

Any help with this would be VERY APPRECIATED as we would like to avoid letting it sit in a shop. The problem seems to come and go so I have doubts a mechanic can diagnose unless its doing it then and there.

Thank you in advance!

    Hesitation occasionally when car is under load (uphill usually). Seems to only happen when the car is warmed up.

My car is doing the exact same too. Especially once I've been driving around awhile and its well warmed up. It happens when i'm going between 40 mph-55ish. I replaced my ignition switch and was told that the old one they took out was fine and was not the problem. What the mechanic did mention is that the shaking could possibly be from the starter going bad. It wouldn't hurt to have your starter checked.

WHEN DRIVING AND THE TRANS NEEDS TO SHIFT ON MY 2005 VW JETTA 2.5-5 NEW STYLE THE RPM'S REV UP BRIEFLY THEN THE TRANS WILL SHIFT THE SHIFTING IS SMOOTH BUT THE HIGH RPMS WORRY ME.


when vw started to use the computer controlled gearbox system a criticism was the shift was very harsh,to counter this they made it rev slightly before changing.so that you know the system, try this out....without touching the gas.....put it in d and let the car accelerate to its max speed,stop,then use 1/3rd of gas (keep your foot still)and let it do the same...stop,then,if safe,put your foot to the floor,hard, notice when the car changes gear(revs/speed)then if you drive,only using the first1/3rd of the gas,the cars change pattern will alter to suit.......wierd it is.....

VW shaking


sounds like the fuel pressure regulator but first try new fuel filter and maybe clean spark plugs and reset them

Engine shakes and hesitate when started until it idles down


Sounds like its missing on 1 or more cylinders. A check of the plugs and wires is in order, Could be a fouled plug or a loose/bad sparkplug wire. Best of luck.

I have a 2002 VW Jetta 1.8t and when I hit the gas to accelerate the car shakes. When I let off the gas it stops. Also if I sit with the car on it overheats rather quickly. I noticed neither of my fans are...


Your car overheating is either low coolant or its the thermostat. The thermostat is what tells the car to add coolant and turn on fans.
Your tranny slips could be because low transmission fluid, which was the cause with my VW. Or your tranny is bad, which is common with VW.
When your car shakes when you accelerate does it seem like its choking?
