I was driving the mach saturday and at one point I was in third gear at part throttle and the car started to buck and surge. I thought it was me so I ignored it. Then i was coming home from ossning getting onto the parkway, I stepped on it in fourth and it coughed once and then it was fine. Anyone run into this problem before? I'm kinda thinking plugs or the fuel rail pressure sensor....... I JUST PAID THE CAR OFF AND NOW THE BASTARDLY THING IS GIVING ME S@#T

Deff sounds like it could be a plug or fuel issue.

Check your plugs to see what they look like, i don't think they would be your COP's but possibly.

Do you notice it does it more when your low on fuel or does it happen even when the tank is full?

Do you have a cold air intake? How's your air filter?
It is definately your MAF Senser. Take it out and clean it.
Mabey unhook battery overnight too and reset computer.
Trust me , I have pretty extensive knoledge on the Mach 1's
and their issues.

What other issues do you know of? I would agree with you on the MAF but its quite intermittent. I'm almost tempted to say the plugs are fouling a little? I'm running a colder plug cause of the nitrous.I'm gonna drive it to work tomorrow and see if it acts up again.
