I was driving home from a two hour trip today and my car started acting real weird.
I was about out of gas and took a hard corner and the car started sputtering. I figured it was nothing, pulled over and got me some gas.
After filling up, the car was fine. I continued on my voyage home and after a while we pulled over to switch drivers. After we switched, as soon as the car pulled off (Without restarting) it started to sputter again! I was like hmmmnn. This car runs like a dream always, I take pristine care of it.
Well, to cut to the chase, the car will only allow me to accelerate up to 3200rpm’s I can go 15 or 68. It don’t matter what gear or what speed or how hard I accelerate. The car still bogs out at 3200. It’s like the rev limiter kicks in. Even the starts are getting ruff. It takes like 5 minutes to start the damn thing. Nothing has led up to it either, yesterday the car ran awesome.
I checked the code when it started acting up and it was a 14 (Electronic Air Control) after I finally made it home I checked it again and it had become a 48 (Primary Heated O2 Sensor)
I am unsure of what going on exactly. I just changed my o2 sensor a few months back. For the o2 to go out I am getting killer gas mileage, which leaves me at a blank. I am hoping someone can help me out. If you can either post a reply or email me:

Thanks.
when you turn your key on…do you hear the whirrr of the fuel pump?
My first guess would be something fuel related but I may be wrong.
since you ran it almost empty…your fuel pump probably pumped alll the CRAP ion yoru gas tank into your motor… TIP* never run car almost empty… also anotehr tip… try not to pump your gas after the gas truck has came to fill up the gas station…setiments float around and get pumped into your car
Have you changed your ignition coil lately?

Ignition coil…never changed it…? Never changed the fuel filter either.
How would the ignition coil affect the car only at certain rpm’s?
Rather than all throughout the rpm band?
it could be a few things. Like someone else said, the crap at the bottom of the tank could have gotten sucked up. This could have (hopefully) gotten trapped in the fuel filter. What also could have happened is that you overheated the pump and it went bad. You see the fuel in the tank acts as a cooling fluid, but when it’s low on fuel, there’s no cooling. I would change the filter first, and run a bottle of regain though the next tank of gas.

Did you tried resetting the ECU?
The ECU was the first thing that I thought of too.
Well, I had the teg checked out…
Seems my O2 sensor went bad, fuel filter is fried, The big deal was that my Cat was clogged 300+ gong in and a little over 100 coming out…
I bought a carsound high flow cat to replace it, any suggestions on the fuel filter, and type of O2 to use…?
Well, Today I installed the new o2 sensor complete new header back. New distributor cap and new rotor button. Still the same problem after 3200rpm’s…
The car kicks back…like the rev limiter is engaged. I traded out ecu’s, and still the same problem. Could it be the tps or map sensor?
Please help.
Any help will be appreciated.
Thanks,
Nick
yup, maybe the TPS or MAP are bad…

pleather - that reply was ridiculous. Ever hear of a fuel filter?
isn’t the pickup on the bottom of the tank anyways? I run my car empty every week and get 30mpg.
I can’t think of anything.
try to reset your ecu now that you have fixed some things.
It sounds like a pressure problem, either fuel or vacume. You arent losing spark in a cylinder or anything because it will still rev over 3200 on 3 cylinders. It could be whole rotor not just the cap.
If you are in nuetral and rev it up does it still bog at 3200?
I would just play around with stuff, undo your intake tube at the tb and see what happens. Maybe your engine is having a problem getting air???
Heres the thing. Does it actually hit what feels to be a rev limiter at 3200? Or does it just chug and bog at around those rpm’s? If it feels like you’re hitting a rev limiter, then im guessing it has nothing to do with fuel supply, and probably nothing to do w/ you running low on fuel. It’s probably something strange and coincidental. Like what JB10 said, reset your ecu. If that doesnt work, i still thing something is up w/ your distributor. It seems to me to be purely electrical.

I tried to remove the intake, that didn’t work. The same thing happens if I’m in neutral or drive, even when I downshift It just dies out till it hits 3200rpms.
After I reset the ecu again, it says crankshaft position sensor? I am going to check that out tommorow, I hope I get it running soon. I really miss the car!
Thanks for everyones help. It’s really cool of everyone to take the time out to help me!!!
THANKS!
ok i dunno if this will help BUT. i had a similar prob with mine only not the rev limit part… i had a sputtering and it wanted to die…what happened with me is i reved the motor pretty high, and it popped off a vacuum hose on one of the little regulators on the drivers side of the firewall next to the brake fluid resevoir. that caused all my probs… so i just suggest checking EVERY vacuum line in the engine bay…it doesn’t take to long and those little hoses are SO important…remember some of them are long and go under the block…so follow them end to end…hope that fixes it…god knows it is better than a motor rebuild…which by the way if ya over reved it recently…which i did too… u may have a messed up valve…do a compression and leak down check to know for sure…only around 60 bucks…good luck to ya
Thanks for the advice, I’ll try that…Hope thats it!

Stop searching! There goes your problem! I remember seeing a post where the guy had similar problem and it got cured by a new distributor… I’m not saying to buy a new dist, but take a look at the sensor to make sure everything is wired up fine and check in the helms, i’m pretty sure there is a diagnostic page on the sensor…

Your right, you and leftcorner. We determained today that the distributor is shot. So If anyone has one for sale, Please let me know.
Thanks again everyone for your help.
