Hi all. My 92 F150 rwd with automatic trans will shudder under power. Last week it seemed to be loosing power under load. It would rev high going uphill and just not seem to get moving like it should. I replaced the fuel filter and then it seemed to rev and move up a hill like normal except now there is a shudder when the motor is under power. On level surface is seems to cruise fine but the shudder returns as soon as I give it a little gas. Motor doesn't want to die or anything. I toggled between tanks in case it might be the fuel pump but there was no difference.
Is starts and idles just fine. The shudder is new. It has a 5.8L and 150k miles. Trans was flushed about 6-7k miles ago.
I saw something about checking the CAT on a Bronco in another post. Stated it may be clogged. Is that possible for this rig? Where would I check? Could it be the universal joint at wither the DIFF or Trans going out?
Any suggestions would be very welcome.
Thanks!
