Well there is a rev limiter built into the pcm on your car. It is much lower rpm's in park and neutral. When u hit the rev limit of a particular gear selection, the pcm starts cutting out the injectors(fuel). This is normal. As far as the jerky feeling, the only thing I know of is a service bulletin that may apply to your car. It involves a revised torque converter for the transmission. It would only apply if your feeling this at speeds of approx 35 mph or higher when the torque converter lockup engages after a shift. Ask your dealer about a possible tsb for this if you think this may sound like your problem or search for tsb's(technical service bulletin's) yourself on the internet.

I have a 98 passat 4cyl turbo and my oil light and now engine light is on. Took it to checkers for a diagnosis and they couldnt read the computer. Just passed emissions 4 days ago and they had to try 3 times to read the computer. What are some reasons this might be going on?

SOURCE: runs rough under load ,stalls

Hi

one of 3 faults

1 MAF sensor also Known as air mass sensor
2 EGR valve, this is most common with the 4000 rev limit and a top speed of say 50 mph
3 air leaks or tears in air pipes or poor seals.

I would be tempted to clean both the EGR and MAF sensor before spending any money though, these parts ofetn work much lonegr when clean

Whens the last time you change your fuel filter. The other problem could be the fuel pump. Our you using Bio Diesel or regular Diesel ?
Some Bio Diesel will not burn hot enough to give you the power.

Could be fuel or ignition.
If the coil or ignition is weak, you may not have enough power to fire the plugs under load.
And if the fuel pressure is low, you may not have enough fuel under load.

The accelerator pressed does not give full rpm


just about all cars with a computer have a rev limiter so you don't over rev it spinning a engine without a load is more harmful then with one this is normal

When turn on the car in the morning, i accelerate and the revolutions up to 6,000rpm normal. In 3 minute when the car up the motor temperature to the normal operation, i accelerate and the revolutions up...


To begin with, if you are revving a cold engine to 6000 RPM, you are asking for a blown engine. Most OBD vehicles are equipped with a rev limiter that will cut off fuel at 3000 to 4000 rpm to prevent you from over-revving your engine and blowing it up. If yours is revving to 6000 RPM cold, then the rev limiter, for some reason is not working while it is cold. I have no explaination for this. The best thing I can tell you is to stop revving your engine so high when it is cold unless you really want to see what an engine looks like after is has gone off like a grenade.

The eng. will not go over 2000 rpm


disconnect the throttle cable from the throttle body and try to rev the engine

if still cannot rev past 2000 then suspect MAF (mass air flow sensor) or the throttle body...remove the snorkel and check to make sure the throttle plate is moving freely

finally, if when the accelerator cable is removed and rpm's rise above 2000 then suspect the accelerator cable and/or gas pedal

Why does my 2000 dodge neon violently **** when i'm in passing gear


If the car is not getting into passing gear at all, check the kickdown cable from the throttle body to the transmission, to see if it's broken or binding. Also check the throttle body itself for smooth operation.

If those are okay, then check the throttle position sensor for proper output voltage. That should have thrown error code 24 if it failed.

As you pointed out, your engine has a rev limiter to prevent engine overspeed. As you approach redline rpm's, it will cut the fuel supply. If this is happening at lower rpm's than it should, then the limiter itself could be in trouble.

I hope this helps.
