Pinging
98 F-150 with 4.6 romeo. Going up hills or romping on the gas causes pinging. I've run Lucas fuel system treatment, X1-R fuel system treatment, and a bit of 93 octane gas in there and notice no difference. Maybe it's just me but it seems to be a real dog on hills and on the highway the slightest incline makes it a battle to hold 65 mph. Don't know if that is normal for said truck/engine combo or an indication to the cause of ping. Any ideads? Thanks.

(I've used higher octane gas as well, no real help..)

It's about time for a tune-up. I would suggest Motorcraft plugs and wires. Not a whole lot of fun, but it can make a BIG difference. Also a fuel and air filter. Let us know and good luck.

Keith I noticed your problem posted I have a 97 F-150 and it has 126,000 on it . Mine started doing the pigging a about 97000 but i have had good success with putting shell 93 octane in. I know that it is different then what other peolpe have told you but it did work for me. And I also did a complete tuneup plugs, wires, feulfilter.

For me anyways, a complete tune up didn't do it. And I JUST had it done. I know what Keith's talking about... it's not constant, only when you go up hills, or try to give it a quick boost.
I'm a novice, but do keep up on my tuneups and oil changes. Doesn't seem to help all that much, for me anyways.

Pinging slowly destroys the engine, which is why I'd like to get rid of it! No way am I going to constantly run 93 octane in it. Costs enough to fill it with 87 as it is. I plan on doing the plugs and wires soon. I'll use the Motorcraft double-platinum plugs but not the Motorcraft wires. They want far too much $$$ for those. I can get wires at a local parts store for $65 with lifetime warranty. I took a look at the air filter today and it's as clean as it would come out of the box new. Fuel filter is an unknown so it's probably just gonna get done anyway. I'm going to try and get my hands on a OBD-II system that displays real time PID values. If not for this event I plan on purchase of one in near future. I'm putting my money on MAF so far but will post my findings when they occur.

i diffently understand not wanting to put 93 in all the time but it does work. I also known the motorcraft wires are expensive but they seal better then aftermarket, they have a lip at the top that keeps the dirt out rather then letting it fall in.

Cleaned MAF this morning. I was gonna use carb cleaner but it's in the trunk of my car which isn't here. Anyway, I used some alcohol in a spray bottle and it didn't do a thing, lol. I left the battery disconnected for like 15 mins too. Maybe it just doesn't like Shell gas? I'll try Mobil this weekend. Changed the fuel filter also.

Have you replaced the plugs and gapped them correctly?
That alone could make a huge difference, with 92k on its time to replace them if you havent already.
Running higher octane is a temporary fix at best, especially since the computer will not adjust timing to take advantage of the higher octane unless you have a chip.
