Default Issues 95 Corvette

Hello everyone. I’m thinking about buying a 95 Corvette with 103,000 miles from a local dealer in my area and I am hoping to gain a little insight from you guys. The car is a good deal price wise but it has issues. I test drove the car and noticed a stumble at around 60 to 70 mph, my first thought was need a tune up. Then from a stand still I attempted to accelerate rapidly and the car bogged out but was fine once I got off of the accelerator and eased back on. Finally I noticed black soot on the rear panel just above the exhaust on each side. My question is does this sounds like any major problems? Any help would be greatly appreciated.

Sounds like you need to get it scanned for fault codes. It is probably running rich, the question is why.

With that many miles, a major service interval is in order, unless the car is well documented and the previous owner can prove in writing it's been recently serviced.

I'd have the car checked out by a reputable Vette mechanic, then look elsewhere if you decide the car doesn't pan out.

Just A WAG, but did you notice any lights on the dash when you stood on it from a dead stop? Did you feel the gas paddle come back up at your foot? They have traction control that could be doing that. It's called ASR(Acceleration Slip Reduction) There is a button on the drivers side dash to turn it off.
Is the Service Engine Soon light lit?

I can not recall feeling the gas paddle come back up but I did notice the Service Engine Soon light come on and go off mostly while driving at hwy speeds.

If the SES light came on that means there are trouble codes stored in the computer. Search around here for the correct method of retrieving codes for your year(I have a 93) or take it to AutoZone and have them check it for you. Or the dealer should be able to have someone retrieve the codes for you.

Does it idle ok? Does the stumble only occur at higher RPM's? High rpm stumbles could be opti (distributor) related.

Check the condition of the plug wires, too. If they're dry-rotted and arcing, then....

Possible Opti-Spark issues, spark plugs, wires, fuel filter, scan for codes. These are the first things that came to my mind. Find someone who's reputable and knows about Vettes, in particular the '92-'96 LT1, and have them check it out.

Yes, the car idle just fine. Only when cruising at hwy speed does the
SES light comes on for about five seconds then goes off again.

I've read about the Opti-Spark. Is this expensive to replace?

Dealer pricing varies, put figure $1,000. plus or minus about $200. Most owners also replace the waterpump at the same time. Also, might as well do plugs and wires while you are in there.

Get a mechanic to inspect entire car. and get a total
cost for repairs and then go get the asking price reduce base on repairs!

Could be something as simple as O2 sensors. A scan should help pinpoint the problem. Good luck. Robert

Go back to the car, if interested, and take a paperclip. Make it into the shape of a U. With the key off, insert one end into #4 terminal and the other end into #12 terminal of the ALDL. Turn the key on, don't start, and see what codes it gives you on the speedometer. Write everything down because there are different modules (1,4,9) that means that code is coming from a different location. Post what you get back here for help.

For the mileage, I suspect it will need a few things fixed. If it's a automatic coupe I would say it's worth around 8-9K. Add a little for a 6spd and/or convertible. That sputtering could be the opti. You won't know until the codes are fixed.

A car for sale shouldn't have those problems, if the seller is serious be it dealer or individual they should have the car in proper repair prior to offering for sale. It is really kind of a joke that the dealer didn't go over the car better before putting it out on their lot. If they want anything more than $1000 below wholesale for it I'd look elsewhere.

This car is at a Chevrolet dealership in the bargain bin area. The dealer asking price was $9,500.00. I was able to talk the dealer down to 7,500.00 cash but not knowing a lot about corvettes other than repair can be costly, didn’t know if this was a good deal.
The previous owner was a school teacher who only used the car to tip back and forth to
work. She traded it in on a new 07 vette, so I’m thinking how bad could it be, maybe the poor running condition could be caused by carbon build up from not using proper grade gas and blowing the car out every now and again

Well, okay, but they still should have had their service dept go over it better before putting it out on the lot. $7500 isn't bad, though.
