Driving me crazy. Idles like crap warm, only in Neutral or park. My o2's drop to double digits, Ex 019-031 and even 0. But as soon as I put it into drive, the idle smooths out and the o2's pick up and return to normal. I tried pressing the "TEST" button on my alchy system, and the o2 jump and...

I recently bought a 86 GN with an engine professionally built by reputable builder. My question is my lifters/rockers are quite loud. Fairly quiet at start up when cold, but gets louder when warmed up. Car has roller cam, Morel roller lifters, stock rockers. Excellent oil pressure at idle and...

Bought a car with a data logger but no software. I tried downloading the needed software, but my computer keeps saying I need to install CD for system to work on my laptop. Not sure if theres another way to download it, but I think the CD would be my best & easiest fix.

I need to replace my right rear wheel cylinder. The previous owner said he replaced both with S-10 blazer cylinders. First off, does anyone know what year blazer I should get the cylinder for? And secondly, how do I know (Before buying both & comparing) if they even are from a blazer and not...

For an 86 GN. I broke my resistor when installing a aux transmission cooler. I have a post in the "Parts Wanted" section, asking for one. I have a one fan system. 4 core, Bee Cool aftermarket radiator installed. Never runs higher than 185. But, if theres an easy way to bypass it altogether...

I have the single fan setup. Was working fine until I removed it to install a tranny cooler. I must have bumped it b.c. it is broken where the bottom wire comes off the steel coil. Thanks.

I was wondering if anyone has had this problem with their Tilt Steering column, If I put too much pressure on it, it "skips" down, as if I pulled the tilt lever and lowered the steering wheel onto my lap! Is this caused by the 4 loose bolts down in the column? My wheel doesn't feel loose...

Anyone know where I should start? Highbeams work fine, but indicator doesn't. Just bought a 86 GN. Owner said he had it out and rebuilt @ Caspers. Just wonder if he could have left a connector off or if it could be something inside the inst panel. Or if anyone knows where I can find a...

It was a 2012 Porsche 911 Turbo at Las Vegas Exotics Racing! What a blast! I never drove a car that could turn and brake like that! I think my GN would have beat it down the back straight away, untill maybe,, 120, but no way after that. And when I came to the turn? Not gonna happen. This car...
