Hello everyone,

My RPM's are going up and down at idle. Not extremely high, but its like I'm pumping the gas pedal only I'm not. It also will not drive, when I push on the gas it sputters pretty bad. Enough to rock me back and forth in the seat. We live on a hill and it will not even make it up the hill. It happened pretty suddenly. I made it to work and back the other day (usually a 5 min drive, took about 8-10), but the next day I tried to do the same thing and it just wouldn't do it.

I've read a few threads on this forum and tried a few things with no luck. I've replaced the MAF sensor and cleaned the throttle body but neither worked.

MY check engine light is on and I'm getting knock sensor and camshaft sensor codes. However, I've had these codes since I've owned the vehicle (about 8 years now) even after replacing them. So I don't think these two codes are the issue.

Here is a video I took so you can see/hear what I mean...

Thank you in advance for helping.

 

I see that your check engine light is on. For us to help u go get that check engine light scanned and right down the codes and post them back on the forum

 

Maybe because the engine is running on fumes/the gunk in the bottom of your tank? I didnt know it could go below empty and still halfway run. Haha. Try putting some gas in it.

That is a classic, no doubt

 

My fuel gauge isn't working either. It's always on empty. There is plenty of fuel.

 

The video won't work on my phone. Does it stall out below 1000 rpm? I had the stumbling too and lack of response when stepping on the gas, my head gasket was going. I'm not trying to be an alarmist

 

Post the codes.

 

I posted what the codes were in the original post. But specifically the numbers are P0325 (Knock sensor) and P1335 (Upper crankshaft position sensor). Like I said those have been there since I purchased the car 8 years ago, and the codes show up even after I replaced them, so I don't think those are the issue.

Also, specifically, I used a different code reader this time and after the code it said.. "knock sensor 1
circuit Malfunction
Bank 1 or 1 sensor"

Don't know if that helps or not. Is that an ignition coil? I replaced those recently so I wouldn't think so. Or maybe I just bought crappy ones?

 

Check your cat? O2 sensors? How many miles are on the car?

Edit: I have a similar issue, but I'm running cat-less and missing an o2 sensor. (inb4flame it's getting put on tomorrow). But I have a bad sputter when it's idling and warmed up completely.

 

Check vacuum leak.
