High Idle, exhaust man glowing red

clarkrc82 · 11-04-2009, 02:13 AM

it hasnt been timed because its idling at 2000rpm. cant time it when its that high.

Yeah the oil was mixed with the coolant. Its had 2 oil changes to clean it out.

No burnt valves either. No smoke, and this sounds dumb but for idling high it runs really smooth, no vibrations and it doesnt miss fire. And when it does drop down to normal it runs smooth to.

I am completely lost with this car, Ive gone over every hose and electrical connection and everything seems good.

I mean that I hope you thoroughly flushed it before the car was stored. If it sat for four years with the crank and bearings, etc. sitting in water contaminated oil then things could go bad real fast... rust does that.

If the manifold's glowing red think about what's happening to the valves...

I've tried... I'm done.

No I have checked that S&%T 3 times now, every thing lines up. The only issue I have is with this http://www.cygnusx1.net/Supra/Librar...aspx?S=IG&P=19

It says "align the grove of the distributor housing with the protrusion on the drive gear" there is no f%&kin "PROTRUSION" on the drive gear, only the grove on dis housing.

Ran into same problem with mine. The distributor for the 87 and I guess 88 7mge has a round circle on the shaft that you line up with the line. That trough me through a loop as well, the sucky part is that the circle is huge and you cant tell if its a tooth off or not as you have figured out now.

Yeah, some distributors/CPSs only have the pin to go by, no other hatch mark, but most people get that. If you're off by a tooth you'll find that to get the timing close to where you want it (10?BTDC) you'll have to rotate the distributor/CPS pretty much as far as the slide on the housing will allow. If this is the case, you're probably off by a tooth. IIRC, properly lined up and zero'd out the timing advance should be close to 0? with the bolt centered in the oval hole.

Clarkrc82, if you have a question about something... ASK. I don't mention these things for the sake of a cheap laugh... and you're welcome.

So I finally timed it today, and set it at 10 btdc it starts jumping up and down from 1000rpm to 2000rpm

It starts doing that around 5 btdc, it jumps more and more as I bring it to 10 btdc. If I set it at 0 btdc it doesnt do that at all. I still need to get an alt though so I dont know if runnin off the battery affects anything. Im not throwing any codes

I have a question, I pulled out and tested the isc and it checked out ok resistance wise but I couldnt get it to move when i applied voltage to b1 b2 and then ground out s1-s2-s3-s4? when the car is off its supposed to close all the way? Its looks like its all the way open when I took it out.
