Today, I was driving my car down the highway for about an hour or so when all of a sudden, my car just lost alot of power and would not go past 60 mph or 3,000 rpms..It started making this wierd noise like my axle was knocking up against something, but I didn't see it hitting anything. Would anyone know what is possibly wrong? Any help would me much appreciated..

Thanks

 

when you throttle it, how does the car respond? If it is a rough response and very hesitant, you might have fowled out your spark plugs. Replace them.

 

Oil starvation will limit the engine to 3000 rpm on a 5th Gen. I get this in autox alot. The knocking sounding could be a resultant internal engine damage.

 

Whenver I throttle it, I have the same response as always until it reaches 3000 rpms, thats when it hesitates and won't go any further. The kocking sounds comes and goes away....I checked the oil, and I had enough.

I checked the spark plugs, and they all look good..

 

when i fouled out my spark plugs they looked fine also. when i replaced them my car ran 100% perfect, i recommmend buying a new pair and seeing if this is your problem. you dont have to go out and buy 15$ plugs necessarily, but the problems i had sound like the ones you are having. you might want to swap out spark plug wires also. good luck

Alright then, I'll do that later on today whenever my brother comes back with his car. Right now, whenever I had my friends boss fix my car, he put Bosch spark plugs in. At first I didn't think anything of it, but then I was thinking that those may not be as good as the NGK ones that normally come with Preludes...I'll just go out and purchase another set.

 

I changed out the plugs, and its still doing the same.....Do you think it may have something to do with the tranny? I have about 90K miles on it

 

Could your catalytic converter be melted or clogged up?

 

I took it off the other day, and it looked just fine. It had a little bit of water, but nothing to really be concered about..

 

make sure your plugs are gapped properly. try changing your spark plug wires also.

 

autolite plugs. They are cheap, but do a decent job as test bitches when you just wanna "rule something out."

Also, I'm not a guru on 5th gen electronics, so I might not be much of a help here...

But I would start with the basics. How long has it been since you've changed the rotor button and cap? What kind of gas are you running? Have you checked to make sure the dist is still on correctly and not retarded or advanced too much? Are your plug wires still good? If the oil pressure is low for some reason, or the sensor that monitors it is bad, then it could cause this. How many miles do you have on the motor?

 

I changed the plugs, and its still doing the same thing. I go to Cheveron to buy gas all the time. I haven't changed the rotor button ever. The distributer hasn't been messed with. Plug wires are still good. I added a little more oil into my motor. I have 20K miles on this motor.

 

try and see if it'll pull a code... that's the next step.

 

How do I do this? My check engine light isn't flashing or anything...

 

If you hear any engine Knock, you engine is blowen or has no oil..... The only thing that ever might cause this is your Cap and rotor. your engine is not getting spark causing the rods to misfire and knock.

 

I'm not hearing any knocking whenever the motor is sitting there running.....Well, today I went out there so that I could move it and now it doesn't even wanna move. It goes into gear just fine, but it will not drive. I'll put it into gear and all it does is just sit there.....

 

when you give it gas does it knock? Check you tranny to see if there is any fluid in it.

 

Theres no knocking when I give it gas....I'll check to see if theres any fluid in the tranny tomorrow....

 

sounds like multipul things, but first sounds like a broken axle/broken diff. why it won't go above 3k is beyond me....broke crank? thats the only part that would also prevent the car from moving at all.
