I'm considering upgrading to a C6 and I was hoping to get a few questions answered. Currently looking at either C5 Z06 or C6. Shopping around, I've narrowed it down to C6's between 2007-2009. Unless I find a deal on 2010's but that's not likely unless it's new. There are so many C6's out...

Hi Everyone. I have been a member here since 2003. I currently have a 1991 C4 Base Coupe. In the past 7 years I have spent a lot of time and $$ making my C4 as good as possible. The car is nearly perfect except for needing a rebuilt on her shocks, new weatherstripping, and new rubber on her...

GM Junkie you out there? Need your input! So back in 2003 when I first got my C4, my Vette had squeeling brakes when they got hot with some noticeable brake shudder. The previous owner has installed Autozone brand brake pads to save $$ and I knew the pads did not fit properly and that caused...

Wanna know how to get 330 hp from an L98? How about just an additional 30 hp? Or maybe how to replace that aging window seal? C4 to C5 brake upgrade? Here is a nice reference point for things you've always wanted to know or do to your C4. 1984-1996 "C4" Technical Articles | Corvette...

GMJunkie, thank you man! I was finally able to replace all eight of my 1991's spark plugs! SUCCESS!! I was having the most difficult time replacing the last spark plug in Cylinder #2, the one on the passenger's side closest to the front of the car. I tried everything short of removing that...

Just wanted to share this confession with the Corvette enthusiasts in this board. About a month ago, I bought a Mustang GT. I know, I know….it’s a Ford! The model is an S197, which is the model BEFORE the current cosmetic redesign. The current Mustang is really just a mid-life makeover of the...

I saw a major crash the day before Christmas right near my house. I driving my Corvette behind a group of cars and we were approaching an intersection. We were moving at about 50 mph. There was Toyota Camry sitting at the intersection waiting to make a right turn into our direction of travel...

There is a strange rattling noise inside the engine compartment of my Corvette that is present only when the engine warms up, it is at idle and in gear. It sounds like it's coming from the right side of the engine compartment. I tried tracking it down by popping the hood, letting the engine warm...

I need to know what is really going on with my Corvette. In 2008 my '91 L98 Corvette began idling rough a day after a long drive. It felt like the car had a vacuum leak at idle. It would also surge at small throttle openings. At 35k miles, back in 2003 I had the car tuned up by the dealership...

This story is a bit long and winded but it does have a happy ending--at least so far. Time will tell. My 1991 L98 has about 53k miles on it. The car is fairly stock with an automatic. It does have a Corsa cat-back exhaust and K&N open box and filter. Back July, on a very hot summer evening...

Hello everyone. It's been a while since I posted here. Life has been up and down for me lately and haven't had much time to enjoy my Corvette. However, things have settled down a bit and now I am enjoying driving the 'Vette more and enjoying it with the wife. My ride is a 1991 Corvette, L98...

This is really Two questions in one post. :chuckle 1) I noticed for quite some time now that my Corvette has a slight case of bump-steer. It usually happens at low speed (parking lot) when I go over a speed bump at the rear axle, the steering wheel jerks a bit. The other day, I noticed it...

We've owned our 1991 C4 for several years now but have never really taken her on a long distance drive. Truth is, although we love our 'Vette and drive her on weekends, the thought of taking her on a multi-day trip has never been an option because our young daughter always came along. Well, this...

Please give me your honest evaluation of my FX3 Shocks. I have attached photos. It is from my 1991 C4 with 49k miles on it. The shocks are original FX3 Bilsteins. I took my Corvette to my mechanic for some electrical work. He told me that my front shocks are shot! He said there was a large...

Just got the Corsa L98 system installed on my 1991 Okay. Before, I had the Dynomax system w/ Y-pipe crossover. I thought those were not bad but definitely had resonance at 1700-2000 RPM. But these Corsa's....wow! Awesome! They emit an exhaust growl that sounds like 60's Muscle car with a...

Got a pair from my local Pep Boys. They're sold as a complete headlamp and not as a replacement bulb for my 1991. Took me about 45 minutes to install both. It was very easy. Well I got to test them tonight. Holy Cow! What a difference! Not that my old halogens were bad, but the new...

Last Xmas weekend, the wife and I took our Corvette out for a daylong drive in the mountains and deserts of North Eastern San Diego County, CA. This part of Southern California looks like it came straight out of that Marlboro commercial. Remember those? They called it Marlboro Country. I...

Did anyone notice that on the new Mid America catalog, Corsa now is offering their exhaust for L98 C4's? This exhaust was previously only available for the LT1's and LT5's. The Corsa's are suppose to have the noise cancelling construction, which eliminates resonance on all C4's yet provides...

My 1991 seems to have three sources of interior noise: The drivers side mirror vibrating. The exhaust resonance. And a "ticking" noise coming from the rear hatch area. The ticking sounds like something is hitting either the metal latch or glass. It happens when the car is riding on bumpy...

The Service Engine Soon warning light has begun to go on in my 1991 L98. According to the owner's manual, I should take the car to get serviced immediately. However, it doesn't explain why it goes on or what it normally goes on for. At first, the light went on for a few seconds while...
