    News: Water pump and optispark.

    Weep hole hose Yeah, I've seen a few folks drill and tap the weep hole to attach a hose which is an excellent idea (hello GM engineers). I thought about it but doing these kind of modifications usually go wrong for me. I'd probably get shavings in the pump and be replacing it again. The pump I...

    News: Water pump and optispark.

    Hi folks. I've never posted here before but have some information ya'll might find helpful. I always look around here to learn how to deal with issues concerning my '96 LT4 and it has helped tremendously. Thanks for your help and maybe I can contribute as well. Started having a very slow...

    best aftermarket shifter for a 1990 six speed

    Please help me identify my shifter. I have a lot of shifter noise in my ‘96 LT4. I posted earlier to see if others are having a similar problem. Doesn't seem anyone else is having this problem unless they installed an after market shifter. So, now I'm suspecting the previous owner may had put...

    Newbie here with some problems with my 96, can you help?!

    Congrats on the new LT4. I also have a 96 LT4. Too fun! The reverse switch is a good bet. I had to replace mine at 65000 miles. Also, I had problems with overheating. Turns out the radiator was just covered in road junk. I sprayed it off through the opening on the right side with a water hose...

    Question: Front License Plate Poll

    Derek, I visited Melbourne way back in 1993. I don't remember seeing any Corvettes. Is the driver side on the left or right on your Corvette? By the way, I like you plate idea. Does it make a thump when it comes up?

    Question: Front License Plate Poll

    Ted, you've foiled my plan! Just as I was to working out how to get those three bales of mary jane in my Corvette, you've shut me down. It is, in fact, the vehicle of choice for smuggling pot. Thanks you for your thoughtful insights. Alas, I see the light! I have changed my ways. Now I see that...

    Any recommendations on where to get my injectors cleaned / matched?

    I had my cleaned by RC Engineering a couple of weeks ago. I sent them in on Friday, UPS second day. Got them back the following Friday, also UPS second day which means: they got them on Tuesday, serviced them immediately then shipped on Wednesday. I'd say that's great service. My LT4 is running...

    Question: Understanding wireing symbol

    I don't know if I can be of any help here but when my cruise control quit, it turned out to be that the vacuum line next to the battery had collapsed. It almost looked burned or something. I really don't know why it failed. I cut out the bad section and put a small hose in its place. Also, a...

    Question: LT4 Shifter Noise

    I have a rattle noise coming from my shifter knob, particularly during loading. It seems I can reduce the rattle by pressing on the knob cover or holding the knob tightly. It could be my imagination that the noise goes down because I am covering the knob more. I've replaced the key and also put...

    Question: Front License Plate Poll

    Thanks for everyone's reply. I know this isn't the topic of the century but I've always wondered about other peoples experiences with the police when it comes to front plates. I've run without a front plate for the last four years without trouble. I was even pulled over once in Southern Colorado...

    Question: Front License Plate Poll

    I live in a state that requires a front license plate. However, I think it is ugly! I choose to leave it off and put my 'Corvette' cover on. I see a lot of other owners that do the same. Just curious, How many of you folks do not put on the front plate even though it is illegal to do so where...

    LT4 Injector Pulse Width Question

    My injectors came back yesterday from RC Engineering. Two of the injectors tested as "dripping" for the pattern test before cleaning. All tested excellent after cleaning. I installed them and tested the fuel pressure without starting. The pressure went to about 45 then dropped to about 40-41...

    LT4 Injector Pulse Width Question

    Thanks for all the help and suggestions. This is a tough nut to crack. The fuel is so rich, there are half-dollar size black water/carbon puddles below my exaust pipes. The problem appeared quickly. I was out driving with my son looking for a car to buy him. It was over 90° that day. We got back...

    LT4 Injector Pulse Width Question

    I would appreciate any help. "The Bullet" has been sitting in my garage all summer. Withdrawal symptoms have become unbearable. I need a fix for me and my Vette. I've been troubleshooting my LT4 for over two months, off and on. The problem is the fuel mixture is far too rich. It smokes and...

    Help! Fuel pressure low, 25 PSI, then zero.

    Hib and Aurora40, Thanks so much for your replies. Just to show you how inept I am, I just learned about, and purchased at Checker, a tool that is commonly available to remove the quick disconnect fuel lines. I had no idea. I haven't done any car repairs in many years and am not up on current...

    Help! Fuel pressure low, 25 PSI, then zero.

    :thumb Thanks for giving me some ideas. I forgot to mention I also replaced the FPR with no help. I think you're right though. I do have a leak somewhere and with no gas coming out of anything I'm thinking it might be an injector is stuck open. This car only has 60K on it and hasn't been driven...

    Help! Fuel pressure low, 25 PSI, then zero.

    With a fuel pressure gauge installed, the pressure reads about 25 PSI for 2 seconds then drops to zero, ignition on, without starting . I expected the pressure to last only 2 seconds as described in the factory service manual but the pressure is well below 41-47 PSI and it is my understanding it...
