Hi Everyone

My 99 Disco II with Ace continues to be a great vehicle except fot the annoying:

1. Service Engine Light ON- As the result of some stuttering when in 3rd gear going to 4th. I have given the care two hits of Seafoam since I thought the cylinder to valve could be sticking abit.

2. Solutions - The car has 65K as I purchased in 2nd hand. I will be getting the misfires codes today and will start there. Also I am planning to replace the plugs and wires since I presune the originals are on it.

3. Question: Could this also be a gas line issue??

Or is anyone having the same problem. I added new tires and shocks to the car which now drives great except for this,

thanks for the help!
