It has been a long time TB but my 945t has sat for 2 plus years sadly. It ran when i last parked it and im pretty sure i put stabilizer in the tank but i cant get it to fire up with starting fluid. I dont think it is getting spark which i believe drives the fuel. Can the crank sensor go bad by...

1991 b230ft. Blew a head gasket 6 months ago and finally got it back together. It ran fine before but sat for a while. Now I can only get it to start and run if I manually operate the fuel relay. Replacing the relay with a brand new one won't help. So the question is what signals the fuel...

There is a device connected to the condenser that looks like a black can. I believe this is the pressure relief valve. My system is leaking from here. The AC system works fine otherwise, as long as there is enough pressure inside to keep the compressor running. Is this part repairable or must...

Since A/C isn't searchable I am having trouble finding info on the problem with my standard temperature control A/C system. My problem is that since the temperature is pushing into the 90s down here, my A/C isn't working so great. It only blows cool when I have the vent selector set to mix...

I let my 760 sit for over a year neglected and unloved. Now that I got it started up and running my knocksense is going crazy at any RPM over idle. It runs a bit rough and I get a lot of rumbling/popping from my catless 3inch exhaust. Clogged/stuck open injector? Stuck valve? The engine does...

The MS guys seem to have a means of reading Intake air temperatures, but how do all the other guys do it? I found some commercial gauges for $250-$300 but think this could be an easy homebrew solution. I think ambient + cold-side readings would be pretty cool. Anyone have any input?

This has most certainly been covered, but how do I activate the cold start injector? I haven't actually inspected it but I imagine it has 2 leads on the connector. Do I simply supply the proper voltage to it? Or does it need a certain signal to tell it to fire on and off?

I am going to do the e-fan conversion on my '91 945 TI. I ordered a few switches from saabsite.com, an 82/77 and an 89/84 (celsius, of course). Is the 82/77 too cold? I imagine it could potentially run forever depending what thermostat I have installed.

My Stock radio hums and squeels very loudly when I first start the car and it has been raining out. Once the car warms up a bit it stops. Isn't there a device that is supposed to filter out the noise? Where is it/what does it look like?

Got bored tonight so I installed a set of browntops I had sitting around. The car is a '91 945TI lh2.4. 11PSI, 13c, NPR, 3inch turbo back exhaust. Do I reset the ECU before driving it? I am asking because after driving it around a bit, the idle is crappy and at top end it stutters. I have...

Who uses an NPR intercooler with the A/C system installed? Does it fit ok? Does the condensor cause any problems? I'd like to hear other people's input.

I am pretty sure that if I want to tighten up the wastegate actuator then i turn the arm out. Does this sound correct? My problem is that ever since the full 3 inch exhaust was installed, boost likes to creep up to 15+ psi when I initially get on it. I want it to be solid at 12 psi...

I changed the filter and oil in my AW71 with 160K on it and noticed a lot of grit in the bottom of my drain pan. My friend told me that these trannies get pretty gritty after a while. The transmission shifts just fine and doesn't appear to be failing. Is this something to worry about? What is...

I ordered up a new master cylinder because I am getting classic symptoms: first pump of the brake is fine but letting off a little and pumping again, the pedal goes closer and closer to the floor. My question is: could this be anything other than a failing master cylinder?

'91 945 turbo. I searched a bit and found a few threads discussing the problem but didn't find anything conclusive. My power steering is SUPER touchy, so much so that I think there may be something wrong. Is there a check valve or anything that may cause the power steering to be over powered? I...

91 945 turbo, with NPR, all else stock: So I installed the full 3 inch system from thelostartof (1 cat, 1 muffler). I uninstalled the MBC so the turbo is at stock levels. When I floor it the boost creeps all the way up to 12 PSI. With the stock exhaust it only went up to 8PSI. Is this unheard...

How much oil should a redblock turbo engine with 160K miles use in a 3k mile period? None (or very little) right? I am about a half quart low with no smoke or visible leaks. What could this be? Should I even worry? /edit 1991 945T

My new Ride. A '91 945 Turbo with 159K miles. My immediate plans are IPD turbo cam, NPR, full 3 inch exhaust, boost gauge, MBC and HD rear shocks (it's a little bouncy now). Not sure about the attachments (haven't posted in a while)

Has anyone used IPD's automatic overdrive blockoff plate? It seems pretty inexpensive and I rarely use the OD switch to switch out of OD.

I installed the big NPR in my 765. I recall people saying they noticed a boost increase after installing one. I did not seem to notice a change in boost. I did notice more off-accelleration vacuum, quicker spool up and the IC and cold side pipe are noticeably cooler to the touch than stock :) ...
