My 1988 302 F-150 has developed a rather nasty pinging problem. (136,000 miles). I just had a new ignition module put on because the last one failed and I had to use AAA... Anyhow, I had used about half a tank of 87 octane (I use the trip odometer to tell how much fuel I've used because we all know how relianle the fuel gauge is in these years!) and put in a half tank of 93 octane, so it was about a 50/50 mix. It considerable helped the problem, but it still pings in 3rd, 4th, and 5th in acceleration. I don't want to start using premium since I've never had to before. Anyone experience this or have any suggestion? As always, thanks!

 

Check your timing. It is supposed to be set at 10 degrees (before)

 

I called the shop that put the ignition module in, and they said that they had reset the timing and to bring it in again,...I think that that is the problem, I'll find out I guess! Thanks.

P.S. I've got 136,000 miles and my oil pressure is running low, anybody else have this problem? Sometimes it's fine, even way better than fine, but, 80% of the time it is very low.

 

I have the same truck, but my oil pressure has always been exactly the same. I am unfamiliar with the fule gauge being unreliable, please explain, I have never heard of this before.

 

The fuel gauges in the 87-91 F-150's, even 250's and 350's, were notorious for being unreliable. If it doesn't always read Empty, it's reading full, or bouncing wildly between. I have personally seen three (My '88, my friends '88, and anothers friends '89)F-150's that the fuel gauge was bogus in.

I found a sort of "quick fix" to the problem. I had a leaky fron tank and had it replaced about a year ago. Whilr the tank was off, I founf the tank gauge and fiddled with it. There was corrosion on the Ground part of the gauge, I scraped at that, and the gauge worked for about 3 weeks before going Kapooy again. I'm sure there are many other members with similiar trucks with this problem

 

My dad used to have a 1984 Bronco that was empty when the needle read 1/4 tank. I had to run out of gas 3 times to learn this. I guess most people could have learned with just one mishap. -- Martin

 

To Whom It May Concern,

I have been having a pinging problem for about three weeks now. It goes away when the spark plug fouls in number eight cylinder. I've been cleaned the debris for about that same amount of time until one day there was no debris. After completing a check of compression "0" it's time for a new engine.
2,800.00 installed. There putting it in right now. Ill let you know if the pinging goes away?> Next week.

separate your two rear most plug wires on the driver's side(7&8?). Keep them seperated thru-out their entire paths.

Hey Chris! How the hell are you? Man, you really should stop by RHC! There's been quite a few changes, and I think you'll like it!

I hope you're doing well, and have your septic all ready for the coming winter. lol.



Take care,
~Chris
