new Distrubutor Cap And rotor
new sparks acdelco spark plugs Part # R45TSX
new spark plug wire set.
new Air filter
Here are the things I'm having issues with:
--Hard to start for the first time in the day--
-Unsure if I should change the coil in the distrubutor or get a replacement starter motor.
--Engine Jitters a little some times
- Unsure if I have to check the timing or something else for this?
--Hear tiny eletric ticking noise
--- no idea all plugs are covered and have no idea what this could be
--Oddly enough no RPM meter ? has giant Gas meter were Rpms normally would be in a car.
--at Higher speeds 50-60 mph it feels like the car is choking a little bit unsure why the back of the car feels like it shakes a little bit. If I let go of the gas a little bit it stops shaking and sometimes I can re-hit the gas and its fine for a little bit but starts shaking a little bit.
-- Bought carb cleaner and took off air filter and sprayed a little in choke area
Well any help would be great!
First off, congrats on owning a Camaro!
I had a 80 with a 231 cid v6 and you have described the same problems mine had when I purchased it.
Here is how I cleared things up;
The hard start problem was mostly a choke problem. The power wire going to the choke on the carb was corroded and not making a circuit.
Cleaned it and the morning start was alot better. Shortly after I noticed that once the car was shut off, fuel vapor was coming up from the carb horn. This means gas was leaking from the carb float bowl into engine overnight and it was empty by morning. Thus it took a while to pump fuel up and fill the bowl before it would start in the mornings. A good working choke assembly will help pump the fuel up faster though still. A few weeks later I took the carb off and did the epoxy fix and no more draining of fuel overnight, was much cheaper on fuel too, search it out for more info.
The engine studders at speed for me was a bad vacuum system. If I remember correctly, one of the vacuum switches around the thermostat housing crapped out, I found it through trial and error. I didn't really fix it but just plugged off that hose since I was going to install a v8 in a few months anyways. What a difference it made, I would go through your engine vacuum system looking for hoses leaking air or plugging vacuum switches off to see what you can come up with.
One of the electric ticking noises I was having was the heater motor turning slow even though it was off, common problem with these cars. The motors can give off annoying ticking sounds that go away when on high. Unplug the motor from under the hood and see if things clear up.
The other electric ticking noise was coming from the funky metric transmission. Never did figure that one out but it was probably a solenoid in the transmission having issues. The trans worked fine and again it was coming out in a few months so I did not chase it further except to diagnose the noise was from the trans. What a strange noise though, I had a 700r4 make a whining noise when the oil filter was plugged but that type of sounding noise was a first.
Anyways, hope this helped and good luck!
