1986 Mercury cougar, just did a full tune up. Now I am getting like a little backfire and occasionally acts like its not catching gears when I try to accelerate. Is this the tranny?

The tranny won't make your engine backfire. Occasionally plug wires can get misplaced on a tuneup. This will cause backfire. Not sure what was all involved in your tuneup, but I would retrace those steps and look for an issue with the tuneup. I say all this assuming that the car was fine before the work????

There is 2 possibilities...A plug wire in the wrong area or you also might need to adjust your carb. You might have it adjusted to get to much fuel.

Sounds like a crossed plug wire.

Could be wrong plugs or gap , firing order wrong by placing wrong wire on plug or timing could be off.

Also it Could be a leak in the vacuum line

Thanks guys.. I took it back today and it was the cross plug wire
