I have a 03 Vue 2.2, it misses at idle, no power under load

Customer Question

I have a 03 Vue 2.2, it misses at idle, no power under load but when you increase rpm to 1100-1200 it smooths out fine. The car has 158000 miles on it. I have checked every thing,coil, ignition mod, map,cts,has new plugs,fuel filter. This thing is driving me nuts.
JA: Are you hoping to fix this yourself?
Customer: Am trying too.
JA: Is there anything else important you think the Saturn Mechanic should know about your Saturn?
Customer: Have replaced ECM,could not comunicate with old one, was told most likely was ECM
JA: I'm sending you to a secure page on JustAnswer so you can place the $5 fully refundable deposit now. While you're filling out that form, I'll tell the Saturn Mechanic about your situation and connect you two.

more info. did you replace the boots on the plugs??? there is also a cap in the piece you removed that contains the coils. it is a very common failure for miss fires.

when we do these tune ups, we replace plugs, boots, coils and the cap. look for black marks in the cap. it is a good indicator of electrical leaking
