Engine misfiring?
I got my car out on Friday for the first time this year and it fired right up and idles perfectly but after warm up I went to cruise around the neighborhood and I could not get out of first gear, as soon as you give it throttle, it pops and runs eratic. I did not have time to check it out, any suggestions on where to start looking for the problem.
Thanks in advance for your input.

Re: Engine misfiring?
After I checked my firing order, pulled the dist cap, check the condenser, checked the timing with a light, and assuming there are no radical changes/jumps /erratic readings when running it up in garage. NEXT
I would pull the valve covers and see if I had any loose rocker arms.

Re: Engine misfiring?
You can try this with #5 and #7 cylinders spark plug wires have to be crossed going to the plugs or induction will happen and cause misfiring. Paul

Re: Engine misfiring?
Maybe the points are corroded or there is moisure in the distributor.

Re: Engine misfiring?
Thanks guys for all your input, I will check it out next week. The gas in the car is Cam 2 from last year, hopefully it is still good at $8 per gal.

Re: Engine misfiring?
Check your spark plugs also.. They do weird things.... Start with the easy/basics.... That Cam 2 won't go bad...

Re: Engine misfiring?
If you put it away last year and it was running good I would first go with a new set of plugs like Rich suggests. Could be carb issues. maybe the Cam 2 ate the accelerator pump up. Check your dwell and make sure the mice did not chew on your plug wires. If it is a BB I bet plugs and maybe some gum from the gas. Suppose to run these cars in the winter you know Jeff.
