Rev limiter like symptons at 3k?

[Chris6050]

Not all the time, but most of the time, my car acts like it's hitting the rev limiter around 3000-3500 RPM. It just bucks, kind of misfires and just won't go any further then 3k-3500, I'm forced to shift. I know it's not the tach being off because I have an aftermarket tach. I heard that it might be the EGR valve, I changed that, but it didn't help. Could it be the fuel filter? Anyone know what it could be? Thanks for any help.

could be the fuel filter. change it and see. it could also be a bad misfire..check all your wires and plugs

 

[SmockDoiley]

Like he said, check all the wires and plugs. If all the plugs look clean, and none of the wires are cracked or burn to create arcing then try the fuel filter. Worth a try since they are so cheap. My bet is one of those 2.

clogged cats

I just changed the wires less then 8 months ago and I have no cats. Looks like I'll try the fuel filter. Is it hard to change? Thanks.

no, super snap easy. Its under the car by the tank on the passenger side. Shouldnt take but like 5 minutes.

you're gonna need a special tool from autozone to get it detached from the hose though...

So you have never changed it? I would start there. It probably needs it even if thats not the problem.

No special tool, just pry the plastic clips out with a small screwdriver.

my 88 needed the special tool to remove the fuel filter.

 

[Chris6050]

Does it matter how much fuel is in the car or should I wait until it's almost empty when changing it? Thanks.

[blkstangman88]

the fuel system is only pressurized when the car is on, other wise the gas goes back to the tank, it doesn matter either way if the tanks empty or full, there may still be a little spillage but not a whole lot

 

[Chris6050]

Ok cool, thats what I thought. Thanks guys, I'll try it tomorrow and see what happens.

Check your engine ground straps and fuel injection wiring harness ground. That wil cause you car to do crazy stuff like that.

Where are those things located and what should I check for? Thanks.

So did the fuel filter fix it? I'm having similar problems

 

[Chris6050]

Yeah I think that it did. I've taken it up way past 3k a couple times since I changed it and it doesn't do it anymore. Although knowing my luck, now that I've said it's fine, it will probably start acting up again the next time I do it.

 

[TheUser]

if that's not it, the timing could be off. Mine did the same thing...my timing was at like 8*...if you haven't played w/ timing, etc though, prob. not it

 

[nitroponynj]

were is the fuel injection wiring harness gruond and weere is the best place to ground the motor? im having bad breaking up problems aND IM ABOUT TO HAVE A NERVOUS BREAKDOWN....LOOL............I JUST WANT my car tyo run right just got done Heads cam intake injector MAF meter instal and they car wil run ok sometmes and then itll break up erall bad other times

Did I call it or what? Today, took it up to about 3500, same problem again. This is driving me nuts. I drive my car like a grandma most of the time and it runs fine, but I just want it to run right the few times that I am actually racing around.

How do I check my timing? I've never done it before. Also can someone give some more info on the eninge ground straps and fule injection wiring harness? I know I have a burnt valve, could that be effecting it? Thanks.

Does it just stop at 3500? or does it slowly rev with no power? (which is what mine is doing )
