Any parts of the egr you clean while on the motor

[s13pignose]

My car recently cut off on me backing out the drive way, with out struggle too. Everything electrical should be fine..since I had batt and alt checked at advance auto few months back, and on top of that batt is an optima. So I've been throwing up code 34 (knock sensor) for a while..with in the past 2 weeks though, its been coming and going, but as late just staying.

I even through fresh ngks in last week to see if it would help..nope. Tried cleaning my IACV maybe a month and a half ago though the intake hose, thinking about trying again..but wondering if it's any parts of egr I can clean with intake and throttle cleaner too. On the motor though, not taking off.

Also supposedly theres' a guy around my way thats good at auto electrical, and gonna let him take a look my car, but wanna do what I can in the mean time.

Try running seafoam through your engine and intake manifold.
that helped with my car awhile back.

1st what motor?

2nd if ur ECU is seeing code 34 knock sensor then ur ECU is prob in "limp" mode, check the knock sensor and wiring.

Yeah I figured could be wiring which is what I'm gonna mention to dude when ever I take the car by there. I checked the ecu wiring for KS up until where it runs along the valve cover..i wasn't about to unwrap all that. Seen a couple humps I thought might have been breaks in the shielded wire, it wasn't. Not from what I saw after cutting back the insulation.

But yeah anyway to try and clean out the egr with can of like intake cleaner. Seafoam I read you gotta change plugs and oil when done..both are to fresh for me to want to change em.

??Any hose I can spray into like I do for IACV

I bet of you take the sensor off, you'll see tiny cracks in the sensor plastic. It needs to be replaced to fix the code. Those cracks make them super sensitive and set the code.

As far as the EGR, its pretty much a sealed system. You either gotta remove the tube or valve itself to spray in there. If its the tube, make sure you open the valve to acess the the port to the intake maifold.

Ah okay..well I felt on the the egr when I rev'd the motor by the throttle body. At first I didn't feel it move, so I pushed in underneath and motor changed up like it was gonna die. I guessed I moved the diaphragm inside,

Then I rev'd it a lil higher and I felt it move on it's own. So I'm gonna skip the egr.

I hope only thing wrong with my car is the sensor itself and not the actual wiring.

Thanks for replies
