I need a knock sensor really badly. Help? Pre-89 7mgte.

[87mgte]

My rear one is somehow broken, and I need to get another one before I can get my car running. I'm in a pretty big hurry to put it back together before the weekend's over, so that's the only reason I posted in the WTB section and this section.

Where's the best place to buy one,
or
Does anyone have one they'd want to sell me ASAP? Thanks guys.

Does it affect anything driveability-wise? Judging by the fact that it's located under my intake manifold, I'd rather just find one now and not have to deal with it later.

It doesn't. Your Timing won't advance at boost and the car will be much much slower.

Your car will be in Limp mode.

Running rich as hell too.

So it doesn't affect driveability, but it'll pretty much constantly retard my timing? Yeah I think I'll just order the part or try to find someone with a used one lol.

 

[Zumtizzle]

I know people who have driven on limp mode for months at a time.

MK2 MR2 and MK3. Owners alike.

It won't retard or advance IIRR. It'll just stay at base timing.

If you can find a Pick and Pull, NA Supras have the same sensor and they never changed, and i'll get you a list of cars with the sensor.

Exclusive to the 7M apperantly.

If you still can't find one. I'll sell you one of mine for a premium, but that shouldn't be a problem finding one.

Thanks for the info. I was getting 10.3 mpg according to the super monitor before, so this might have been one of the contributing factors... running pig rich all the time. My o2 sensor's probably on its way out, too.

Order a O2 from Rockauto.


234-3050 33 bux. + 5% off i just listed up there. You just have to splice the harness on there. Not hard to do, it even came with the crimps and heat shrink.

For now I'll just see what I can do about the knock sensor, but this thread's in my internet favorites cause I'll lookin up the o2 Rockauto part # within the next few weeks. Thanks man.

...The knock sensor is for your pistons/rods knocking. Doesn't have anything to do with your drivetrain or anything as far as I know. Does the car still start?

 

[Darkknight17]

Yes car starts and idle and everything. There is a bad continues leak where the crankshaft pulley hole is, it look like its coming from the left side of oil pan and running down that hole. when i was looking at it it also looked like it was continuely leaking out that hole?? Now the car moved about maybe a foot today. Wont reverse or anything. Very very confused. even if my brakes were rusted wouldnt it still move?? did put w-d 40 also.

Weird... well I'd ask one of the experts like jdub about it, or start a thread in the general Mkiii section if you haven't already.
