Mostly stock, 258 c.i.d., T-176 tranny, Dana 30 front, AMC 20 rear, Dana 300 t-case, 31x10.50 tires, 2 inch body lift
So, I did a vacuum test on my Jeep project this morning...It's running about 21 inches of vacuum at idle, but drops to about 16 inches around 3500 RPM. This is a sure sign (I think) of a partially plugged exhaust system, and maybe why my Jeep loses power under load.
Seeing as how it's the 4th of July weekend and I won't have new exhaust parts until later next week...Does anybody have a temporary fix that will give a little backpressure relief while allowing the Jeep to still be driveable??
P.S. Should add that I don't know where the blockage might be right now, but both the converter and muffler are very old, and could even be original...
