Took the blasty out for a ride in-between raindrops today, and ran good for the first hour. Then started, to loose power especially down low, I couldn't pull out in second gear no matter how much gas i gave it it would stall- and when I stop for a quick break the idle would get high then go back to normal, sounded like it was knocking too- also when I was cruzin say in fourth about half throttle she would start buckin a little when ya let off the gas. Was about 1/2 hour a way from the trailer, so decided to go back early as to not screw anything up. Couldn't go too slow as there are some pretty large climbs we had to do. So I babied it as much as possible, back to the car.
Get it home check compression 150psi three times in a row at 11 kicks.
decided I better do a leak test as the high idle is classic of that, and sure -enough she has an air leak. It's a big leak as it went from 7psi to three psi in about 30 seconds. I checked to make sure my exhaust block off is sealing good as that has been the issue in the past all good there, reed cage two bolts loose, not finger loose but was able to get about 1/5 of a turn from them. Ran out of soap water, and will finish testing tomorrow as 5am comes early.
My question is could a huge leak cause all of these problems? ( High rpm change at idle, Low end power loss, bucking when deceleration, Knocking, maybe pre detonation?) BTW -im running a B9 plug. However I don't know what pre detonation sounds like any one have a sound clip of it on a blaster?
I know I could fix the air leak and go riding and see how she runs but if I may have other issues, I don't want to damage anything.
