I'm sure he isn't the first to find out that Alcohol and Vettes(actually, performance cars) don't mix well.

I finally got fed up with all the issues of the factory GM-Bose on my '90. It sounds good, when it works. By the same token, NOTHING lasts forever. the new technology is cool too. I had my local Best Buy install a new Pioneer 720 receiver with an Alpine PowerPack Amp and four 6" JBL co-axial...

Same thing, just like boating... Just because you can afford the vehicle doesn't mean you should be operating it without some know-how(training.) I see it all the time here. Some rich jerk buys a big boat or expensive car and almost(or does) kill himself and worst off, others too. While...

Especially if you have the ECC system. Electronic Climate Control. There are about 3 or 4 different fuses that contribute to the system with a host of other things. The manual has a detailed troubleshooting flow-chart. Trust us, DON'T Guess. Get the FSM(red cover version) Corvette Central...

Sam I have a '90 too and you need to reset the TV( control cable at the throttle. The TV cable as GM calls it stands for Transmission Valve control. In layman's terms it is the "kick-down" cable. There is an easy procedure for it. Google it or look it up in the search here. It's also listed...

Gene this opti is beyond my expertise. But I would imagine it is like a normal distributor, only it is driven off the front of the camshaft instead of the rear. But.....Having #1 cylinder at TDC on the crank pulley should relate to the rotor pointing to #1 wire terminal on the opti. Then you...

I believe there is in the aldl. I'm not home either. I'll look it up in the fsm tonight unless another member remembers sooner.

That sounds more like a "line-lock" than a parking/emergency brake. NEVER in all my years have I hears of such a procedure for a parking brake.

Congrats!!!! I would guess there was a problem with the old opti. Glad she runs now. Make sure nothing is keeping you from jacking the engine up far enough. Take the through-bolts out of the motor mounts. The trans bell housing should(has to) be up against the "tunnel." Make sure the...

You are NOT being very clear about which bolts are broken. Plenum to runner(on top), Runner to manifold(at bottom), or Intake manifold to head(very bottom). Left(drivers side), Right(passenger side). Don't you have a cell phone that takes pictures. It makes it hard to help when there is...

I had the same problem on my '90 Coupe. You CAN NOT find a replacement connector anywhere. I looked. Here's what I did to remedy the situation. If you can't get the component,....then we have to make one! The 2 poles connect as a common in the original plug. This is obvious since it is...

Thanks Kane.....Good idea.

I've experienced a few where the torx splines are rusted and the torx bit slips in there. OR do you mean the entire head of the bolt is gone(broke off)? If the splines are bad try an impact screwdriver with an extension and either the torx bit or a flat blade on it. Because those are case...

I'm thinking of replacing the mufflers on my '90. Each side of the exhaust is individual and are straight pipes winding from the manifolds to the mufflers along the tranny and drive shaft tunnel. The existing ones are blown out and getting louder every time I drive it. I still want a bit of...

Well, if the pump ran before and now it doesn't; reverse engineer everything you did. Also is the pump NOT running due to lack of POWER or a ground? That will lead you in the right direction. Have you tried to "hotwire" the pump out of the car. Do NOT run it for an extended time with out...

I'd be more concerned with how it will react with the radiator and heater core. Personally, I'd go to a reputable shop like a Firestone and have them back-flush the system and put a new thermostat in.

Are you getting power to the pump? Throwing parts at it can get real expensive. Get a FSM and use the troubleshooting guide. Are all your fuses, fuseable links and grounds good? There are power and grounds going places you'd never expect. For instance, If the 5 amp LCD fuse is bad the fuel...

Gene I have no experience with the Accel Opti's. I've used their ignition products in the past and they are top-notch. Holley now owns Accel, so don't freak out. It's all good. Swapping out the oil pump is a good idea too. The standard Mellings should do well for you. Make sure the oil...

Great accomplishment. CONGRATS!

Welcome to the forum. Drain it down about a gallon or so. That should be sufficient, because you'll have to remove the t'stat housing and upper hose. Gives you more room to work without leaks. How much vacuum is it pulling at idle, Hot and cold?
