Coolant temp sensor is reading -74f according to logger.Gauge on the dash is not working either.Both are hooked up.Any tips? I've done my best to check for breaks / shorts in the wire, don't see any.Do these have a common ground that they need in order to function?Both were...

Basically no if's / and's or but's about it- Head gasket, correct?Was a halfhearted leak down test, just took a compression tester with a quick connect and 150psi into each cylinder at TDC. All were fine except #1 which immediately pressurized the coolant system.Just double checking...

If ignition timing is too far advanced for the gas you're running, at some point, no matter the A/F, you WILL have detonation aka knock, right?

I have read the vfaq and the wiring diagram that comes with the neo. They point to two entirely different wires for the rpm wire. I have tried both wires and can not get the neo to display rpms. It just stays at zero. I have tried changing number of cylinders and all that. No luck. My car...

There is oil on my number 4 runner of my turbo manifold.. last nite the number 4 plug fouled out. I pulled it to find the plug completely black and caked with oil. The compression tests that were done recently checked just fine. Could this be blown head gasket? Or cracked head? There is no...

I have a broken plug on my number 4 fuel injector. Can I get a plug from a N/T car or is it a different plug on the N/T injectors? It's where the pigtail plugs into the injector. Any help w/ partnumbers or what I need to order will be appreciated.

OK.. Long story short:My timing belt was recently replaced and balance shaft removal was done. Cam marks are lined up, dowels at 12 oclock, etc. I'm 99.9% sure that the belt is timed right. I'm trying to set the ignition timing. I put the light on the #1 plug wire and ground the timing...

I have a 1990 Laser RS Turbo, I just purchased from a friend. He recently replaced some parts including the turbo (exhaust side was cracked) with a ported 14b, the belts including the timing belt, and he did the free balance shaft removal. When he cranked up the car after the fact, the timing...
