lol thats normal when you are standing still(ive played with it before)

get it on the road... once going like 20mph+ itll rev all the way up... no idea why it does that, but i know its normal...

clogged cat
fuel pump

get ur fuel pressure and backpresure checked

any codes?

 

its your p/n rev limiter, the vcm switches to the higher rev limiter when you are moving 5mph or faster.

 

no codes,and its not normal .it was running great the night before,now it kinda stutters,it runs real ruff.what p/n rev limiter,is this a sensor .will it make run real crappy,thanks for the help.

 

the park/nutral revlimiter is in the PCM programming and can only be changed with HP Tuners

the cutt off at 4000 RPM in nutrale is normal

the car runing bad is not does it stutter going down the raod ?

 

yes,it stutters pretty bad when driving.so the cut off at 40000 is normal,well that good,1 problem solved,thanks..

 

Just went through this on my 2000 3.8


FOLLOW THESE STEPS:

Check all the wires, make sure they arent cracked, if you haven't changed your wires or plugs in 50,000 miles change them all.

I had to change an ignition coil and all the wires and plugs, still stumbled around and cut off at 4000rpm

I then changed the fuel filter and it fixed the stumble, still cut off at 4000

It ended up being a bad cat, see if the exhaust smells funny or if you hear a rattling coming from under the passenger side, also if your exhaust feels colder and the engine warmer than normal thats a sign too.

Got the cat replaced today (literally) and I have no more stumbles, codes or cut off at 4000rpm

in our cars, rough running like you describe is usually due to bad plug wires. get a decent set of 7.5mm or 8mm wires and prepare to cut your knuckles. wires are a damn b1tch to swap.

hope that helps.

oh, and if you find any metal shrouds or shields on the plug caps when you remove the old wires, be sure to put them on the new wires when you install. or you might have to go through this mess in another year or so.

 

I had that problem not too long ago, same thing engine just cuts out at about 4000, i just changed the plugs and wires and it was fine after that.

 

hey ,thanks alot for the info will change the plugs,dont know were to start,its going to rough trying to chnge these wires,thanks will post results !

 

result=great,great its back to normal.thanks it nwas the damm spark plug wires.

 

I don't know if you fixed your problem yet knowing that you posted this a while ago. I was having the same symptoms as you. I brought my car to a mechanic to get a diagnosis. Came back and they said my cat was literally falling apart inside therefore clogging it up. I was able to have my cat replaced for free by a local chevy dealer because the mechanic i brought it to said that chevy has or had some kind of warranty for the cat itself if your car has less than 70,000miles on it. I called up the dealership just to confirm, and the mechanic was right. So I saved around $500-$700. Got my car back a couple days later, whoa was I happy!!!
