Hard jerking while driving
88 190e 2.3L
Ok, well I got the stalling problem fixed, the crank position sensor. Now the car is jerking really hard while driving. It doesn't start up until after I've drove for a good 15-20 minutes. I've been letting the car warm up to 80 before driving it so it doesn't really seem to be engine temp related, unless of course it is the engine heating up some wire causing it to break connection.
There is no clunking sound either when this happens, or any sound for that matter it just jerks really hard. It gets progressively worse the longer I drive it. The jerking will start out only occasionally and eventually get to the point where any time I step on the gas it jerks until the point where it will just stall out on me after about 40 minutes.
It only seems to do it in forward gears. It doesn't even hesitate the least bit in park or neutral and doesn't jerk in reverse either, but if I punch it in reverse and come to a quick stop it will stall.
I can't reproduce the jerking no matter what I do, stomping on the gas, switching gears.
Another issue, quite possibly realted is that I need to replace my fuel filter again. This will be the third one. Before I bought the car it had been sitting in the woods for about 5 years. It was given to a friend of mine, he replace the fuel pump and filter, had the injectors cleaned, couldn't get it running and then I took possesion of it. Since then I've drained the fuel tank and have put two more fuel filters on it, but the thing is still clogging up filters. Any one have a good ideas of how to get this tank cleaned out good so I can stop wasting money on filters?
heres a list of what I've done so far.
crank position sensor
hours and hours of cleaning
cleaned batter terminals and every electrical connection I could find
checked duty cycle its 50.7
tomorrow plug wires come in
tomorrow I'm getting vacuum hose and replace all of that
I really need to get this thing going, it has the potential to be a great car, not to mention I'm driving a Kia Sephia right now
