If my car is in park/N it runs great and it revs well but when I put it in drive and start going down the road there is a miss. It isn’t constant but it happens every couple of secants or so. I have no idea what is causing it because it doesn’t happen in park/N. It is happens most at about 1700 rpm and up not so much at idle. Any ideas what it could be would help.

some misses only show up when you put a load on the car.

Have you inspected your spark plug wires for burns or cracks? Also, have you inspected your plugs?

I had a fairly decent miss a while back and it turned out one of my plugs was just gapped too small. I must have dropped it on the floor while putting it in.

 

Put new spark plugs in and it still runs like crap. And i didn't have any burnt wires untill after i put the i put the wires back on. and now it runs like crap and i have to replace one of my wires.
