Hey there everyone It's been a while since my last post!
I recently got rear ended by a drunk driver in my 1991 Z28 Camaro Convertible and it's currently at the local junk yard being parted out.
However, I have purchased a 1987 Corvette C4+3 to replace my Camaro.
I LOVE this car!
For a 26 year old vehicle with 88,xxx miles it runs and drives like a brand new car!
I have been noticing a few weird issues with the car though and I was hoping someone could help me out
Well first off I'm curious as to know why my acceleration is like a slow obese cat at times. When I'm under 1700 RPM it'll kick in gear and the rear tires will let loose. But anything above that it, well, doesn't. I find it very odd. I'll put the petal to the floor at 2200 RPM and it'll slowly work it's way up to 4400 RPM. I have a feeling this is TPS but I could be wrong.
I also have a problem with the reverse/back-up lights. The C4 has 4 reverse lights (2 on rear fender/bumper and 2 on rear bumper). These lights only turn on randomly. I'll throw it into reverse and they will not turn on. But other times i'll throw it into reverse and they'll be as bright as day when it's night out. When they do turn on, if I wiggle the shifter they'll shut off. I honestly have no idea what this could be.
I put in a new alternator and battery just for maintenance but my battery levels are still fairly low. After 20 minutes of running time and the A/C on the voltage reads 11.8volts on the gauges. I'm not entirely sure if my A/C is draining a lot of voltage but I know those aren't normal running conditions.
Also, my A/C likes to work randomly as well. When I hit the switch I will hear the radiator fan turn on, the Idle shift, and I hear the internals of the compressor working but no air blows out. Could this be a bad blower motor? When It does work the air that comes out is fairly cold but the air flow is weak. It barely reaches my body even with all the air vents pointed towards me.
And last but not least, there is a slight "bump" or "rattle" sound coming from the rear end. I had it up on a lift the other day and I saw an exhaust bracket was snapped off but when I yank on the exhaust system it doesn't budge. Could the bumps on the road be strong enough to move the exhaust up and down to create the bump I hear? It's a very light knock but it's bothersome.
Any help is much appreciated! I know it's a list but the local Corvette specialists here in Florida are expensive so i'd rather do trial and error with a bit of help from you guys before I dish out some cash
