I have had this truck since it was new and all maint done as scheduled. A few months ago it began to have a low idle miss and I had all plugs, wires, rotor and cap replaced. Still had low idle miss. Number 4 cyl plug was fowled. Had dealer do checks they recommended injector cleaner, then timing change, etc. Paid over 500.00 and still had the same low idle miss. Took it back and then a check for leak down was done and the number 4 cyl was leaking more than 20%. Recommended replacement of eng. Had that done at the cost of 6500.00 and while it runs well I am not happy with this happening at 8200 miles. Not sure if I will purchase another GM product!
