Engine questions for new 72 Cutlass

B-Mann · April 5th, 2009, 04:06 PM

Hi guys, I'm new to the site and just recently bought a 72 Cutlass S. The engine seems to have a miss in it and if you unplug one certain plug wire it idles fine. Any ideas what might be the issue with it? Thanks for your help.

Look under the hood at night and see if there are any flashes of light ...

X2 Sounds like a short, likely bad wires. You will probably want to go the whole nine yards, and replace plugs wires cap rotor, points and condenser. At least that is what I have done in the past. That way I KNOW everything is done, and should expect it to last. I am kind of lazy though, and don't like tearing into the same things repeatedly

Welcome to the site. I agree with replacing the plug wire it sounds like they are cross firing. this happens when the wires are old.

When I got my 76 chevy pu, i had the same problem, replaced plugs, wires, dist cap and that took care of my problem

I was thinking two of his plug wires are switched around...idles smoother??

I have seen this happen with a bad cap too. Its either cracked or arcing between poles inside.

I bought new plugs wires and cap, I will install them tonight and let you guys know if it helped. I don't know how to post images on here yet so if someone could let me know I will post pics of car. Thanks

The back seat? Well, you should be simply able to lift the front end of the rear seat bottom cushion up towards the back of it. Sort of push in and up. Then, the seat back will have one bolt on either side at the bottom bolting down the seat back cushion frame. After the bolts are removed, you have to lift the seat in an upwards motion (towards the roof) to get it to unhook at the top.

Hopefully this makes sense. In my mind, it's very simple. Typing it out, not so much.

Don't forget to remove the arm rests first...
