Ok, I got the fuel problem fixed on dad's challenger, Since its getting the proper amount of fuel now, the car will cruise without surging. I appreciate all your help. The only problem left with the car is what I believe to be a lifter/cam problem. When you accelerate easy now, the car does fine, but when you get on it, the car stumbles and backfires. Also, it has a bad tick at all rpm's, and does not go away when it gets warm. Soooooo, I pulled both valve covers off and disconnected the coil wire, and had dad crank the engine. What I found is that on the #8 cylinder, both rockers barely move compared to the other three cylinders on that head. Also, on the #7 cylinder, the intake rocker barely moves about half the stroke of the other rockers on that head. Now, I pulled the rockers off and pulled the pushrods, they are not bent or anything, and the shafts are installed the proper way, so they are getting oil. I think either the lifters are bad, and are collapsed, or the cam is wiped. The engine is all original, and I can't see why the original cam that has 31,000 miles on it would suddenly wipe three lobes, but it is very possible. I won't be able to pull the intake for a week or so, but I wanted to get some opinions until then. Could a collapsed lifter have that much slack to provide the ticking and the slop to not allow the rocker to move that much, or could that only mean cam? A compression test wouldn't tell me anything I don't already know would it? Anyways, I think this is definately causing the car to spit and sputter at full throttle, and causing my tick, now its just time to fix it. What do you guys think?
