I have a 96 Jetta with 135,000km that has 3 problems which I think may be connected. First, sometimes (well, it's happening more often now) when I'm driving, the car stutters/hiccups especially when I'm driving slower, but still noticable when I'm driving faster. Next problem I have with the car is, the car stalls when I try to start it up, sometimes. When I start it in the morning, or when left unused for a long period of time it starts fine, but if I'm running errands and starting it every half hour or so it stalls. If I start it holding the accellerator and keep the revs up for a while it'll eventually hold when idle. The last problem I have is when I'm driving the check engine light will come on sparatically, usually when I'm accelerating, especially uphill. When it comes on and I notice it, if I press the accelerator more, or just let it go, the check engine light always comes off. So the check engine light will never be on for more than about 5 seconds. I have recently had the fuel injectors cleaned, both my plugs and wires changed, and I don't know if this helps or not, but my water pump was replaced recently too. Any and all help will be appreciated.
