help! car down on power
All of a sudden the car feels down on power, very sluggish at lower RPM's. Seems once it gets moving above 4k it comes alive with full power. Idle is not right, rougher then normal. Car does have a cam, springs, pushrods, pullie, ls6 oil pump, rollmaster, etc. This was done by Mikey at Rapid last Oct and has been flawless up until this point. My first fear was that I broke a valve spring, but I don't hear any kind of loud ticking or any backfires, so I don't think this is it ( I used a stethoscope all over the valve covers). Car is over maintained, so I don't think it is a plug, plug wire, or fuel filter. I have a call into Mikey, but any one have any ideas? I would like to get this fixed ASAP, I was planning on hitting cecil co this week.
