Maintenance needed on Ford E-150

Car Information:
Ford E-150
Year: 2003
Engine Size: 4.2
Trans: Automatic

Issue / Question:
At 90+ mph acts like its missing, now happens as low as 35 mph. Will go a week around town and is o.k. On the highway will go 200+ miles with no problem. I travel often and am currently in west Texas. The van has 78,000 miles. Odessa ford can not help me, no warning lights or no code set. May not be available to stream live, going to New Mexico, e- mail if possible. Purchased new highly maintained, and yes amsoil. Problem started approx. 3200. miles ago, PLEASE HELP!

Answer:

You do know I’m at a disadvantage considering I’m sitting behind my desk in Orlando and you have the van in Texas? If it feels like a misfire it most likely is. If it was mine I would replace the plugs and ignition cables and install a new fuel filter and air filter if needed. Another thing that happens is the secondary intake valves that open to allow more air under wide open throttle sometimes stick or the vacuum valves quit working this also needs to be looked at.

Recommended oil for old engine

Car Information:
Ford E-150
Year: 1993
Engine Size: 5.0
Trans: Automatic

Issue / Question:
I just bought this van, 175,000 miles, runs fine. The last owner just put 5w-20 oil in it, which I think should have been 20w-50 not 5w-20. For now I added LUCAS oil treatment. I am hoping to get another 30,000 or so out of this engine. In the future should I use 20w-50 AMSOIL?? What is your opinion on the LUCAS products??

Also after driving for a while, when I stop and then later restart the engine idles rough for about 1 minute and then clears up. What are your thoughts??

Thanks for your time,

Answer:

Shouldn’t hurt anything, You are right 10-W-40 or even 20-W-50 sounds like a better choice for this old motor. Pull the dip stick and smell the oil after driving, if it smells like gasoline it may have a bad fuel pressure regulator causing the restart miss.
