It drove fine with no ticking 1400 miles from vegas to little rock. The owner told me it was sitting in storage for 5 years. I had to repace the rear fuel pump and sending unit because the gas was old and dirty and the pump didnt work. I drove it with the front fuel pump from vegas to little rock with no problems. I just wanna know whats the acceleration problem? Is it the exhaust manifold cracked or low air pressure from a bad sticky valve making the ticking noise. Ive had for a few months a few weeks ago the ticking started coming from the right side of the engine right on the driver side near the power steering pump. Are you saying I need to do a compression test and see how many pounds of air compression its making? I dont understand or know what a vacumm test is. I did replace the valve cover gaskets and intake manifold gasket but they were all made by felpro and not the original motorcraft,
Your engine is one great big air pump. It pulls air in, mixes it with fuel, compresses it, ignites it and expells it. It creates a vacuum in the intake to draw air in. This is done by the downward action of each piston. Exhaust is pushed out by the piston coming up. If the exhaust is plugged, it can't get all the burnt fuel/air mixture out. Less fresh air and fuel can get in. When this happens, the vacuum pressure will drop.
Find a reputable muffler shop. Make sure they have room on their rack for your units height. It's quite possible either a mouse nest is inside your tail pipe or your muffler has rusted inside and collapsed. For your unit, driving like this is like you jogging with a pillow case over your head. This may not cure the ticking but you'll have a lot more power.
