2003 disc2 rough idle 2-3min after start and experiencing sluggish acceleration during gear changes from 1st to 2nd

 

Not much to go on, so here is a shot gun answer.

Plugs and wires need to be new, not what came with the truck.

IACV - clean with carb cleaner.

MAF - clean only when stone cold and key has not been in the ignition for 8 hours with made for MAF spray.

Any coolant loss?

Any codes on your scanner or Ultra Gauge or a stop by the parts store for a free code read?

Air filter clean?

 

How mechanical are you, how many miles on the Disco, when was it last tuned along with new 8 mm silicone wires and do you have any fault codes?

 

Yes u guessed right, i am mechanically challenged. Thank you for ur responses and i just found coolant all over my driveway this morning, in addition plug wires and plugs will be checked this weekend, air cleaner is new and i will have the code(s) checked also.Sorry for the lack of info but ur responses appear to be right on point. The disc2 just turned 100k. Thanks again and i will keep u posted.

 

If u cant c da leek go 2 partz store and rent coolant pressure tester, pump up to 15 PSI. Make sure you keep coolant filled up, overheating is real easy to happen, even if gauge is still at 50%. Your running rough is likely the first stage of head gasket leak, coolant into cylinders, now the driveway.
