I have been having severe performance problems off and on for the past month or so. Lately the car has been stalling out for no reason, bogging down, or cutting out. I took the car out with DSMlink to read what was going on and to clear the CEL that was being thrown.

3 CELs
Front 02
Rear 02
Knock Sensor

I did as I always try to do, take out the knock. I gave the car a little more fuel and sure enough, all the knock went away.

Fast Forward: Next Day
Knock is back again. I could tell it was really bad when I would step on it, boost would build for about 500 rpms and the car would start shaking violently, obviously fuel cut.

Plug into DSMlink again. Now I have constant knock. At any rpm, under low throttle I have 3.2deg of knock. I absolutely cannot do anything to get rid of that knock. When boost builds (tries to build) knock screams to 12-13 deg of knock...timing gets retarded to -5deg. Ouch.

I talked with my father, mechanic, who has a couple ideas, but he is also fearful of the worst. Fellow 2gnt brothers, I fear crankwalk is upon me.

I have absolutely no money to fix the motor, I just bought a truck and am literally totally broke. I have a place I can store my car for the winter, but I think the car is down, and out, for this season.

*Cry*

wow, that really, REALLY sucks

how many miles are on your car?

and did you disconnect the battery after the fuel cut happened? becuase it will keep cutting until you reset it.

No man, lol Change your front o2 sensor. My car did the same thing. Yours is most likely bad, they cost like 50 bucks for a universal one from autozone. Trust me your car will feel so much better.

Yes ... two things. Replace the 02 sensor and I'd look into replacing the knock sensor as well. I don't know specifically what the dsm knock sensors do when they go bad. However, on my vr4 my knock sensor read 0 at idle and light revving. At over 5k, I saw 8-9 knock and it would never go away. I never drove the car like this (obviously because of all the havoc it wreaks on the timing curve).

Either way, it's something you should look into replacing.

Also, you don't have your fuel cut removed via DSMLink? You can do that you know.

Also try some seafoam maybe or something. Compression test also.

Just some ideas. It is NEVER the end. There is always something to do ... just a question of whether or not you want or can do it .

Knocking really has nothing to do with crankwalk.

It's funny how everyone automatically assumes when their 2G has problems that it HAS GOT to be crankwalk.


Tune the car. Listen to the CEL's and fix the broken stuff.

so take off the oil pan and check for crankwalk. *shrug*

Do crankwalk tests if you think it might be that. Left hand turns in a parking lot with the clutch down is a good prelim test.

Replace the sensors. A dead sensor can wreak absolute havoc on your car because the ECU sees none of the info it needs to see to let the car run correctly. Mine was breaking up gorribly for a day or so and it turned out one of my coil wires had come loose and I was running on three cylinders. Knock at every RPM and huge hesitation and stuttering.

And I assume you have verified base timing and everything is all ready and set up? The car idles and runs in vacuum fine?

It's running again shitheads.

Think for yourself. Question authority does not always mean disagree with authority.

sounds like a failing sensor to me. im happy for you in case.

Replace your sensors....I am sure you were getting those codes for a reason. I can see if you fixed the senors and all this was still happening, but you haven't fixed it yet. Just park the car till you get the sensors and go from there. Don't worry yourslef to death until you fix what it is telling you to fix. Call Conceilli Mitsu...o2 sensors are about 100 a piece. I have a unviersal one for sale and already spliced together if you want to buy it from me. IM or PM me and i will explain all the detials behind it...lol.

Thanks Jerrome, I have some other options first. When I had the car down at the local satan here I made some friends at the dealership with VR4's. One of them is the service dept manager. He has made an appointment for me first thing in the morning to get a diagnosis check done. He said they will pull the codes off the motor and check all possible problems, sensors, fuel, plugs, injectors, etc. They usually charge 1 hour labor for this, but he said he will let it slide this time. Hopefully they help me solve my problem.

Knock is tough to get to. Be prepped for some frustration in getting back there to that bastard.

O2 is easier, so let us know how it goes.

SHE'S ALIVE, SHE'S ALIVE!!

I took the car out tonight, first time since I got it back from mitsu. Car was totally running like ass, but I found out why.

When they got under the car they unplugged the ECU. In doing so it reset all of my fuel settings and set everything to +/- 0. Got everything adjusted after 6-7 runs and now the car is running much better, but still not up to where it was.

Unfortunately, the tranny is still fucked. I can feel it when I start, when I burp the gas, when i shift, and I can hear it all throughout 1st and 2nd gear. Suxor, but at least she is running.

Sorry about the freak-out guys, it wasn't as bad as I thought it was.
