Fuel injector problem.

[Mr. Yuban]

Dear Sirs;
I was looking for some information about my 1994 ford ranger. It has app. 120,000 miles, and it has developed a pinging problem. I use 87 reg. gas. I have had an expensive fuel injector cleaning done, but this has failed to help the problem. The vehicle appears to run better when it is cold & damp versus hot & dry.
Does anyone have any suggestions for a fix, or someone to contact.
Thanks for your time.

Check out this tip: http://www.explorer4x4.com/tips.htm#mas It states it's a cure for a missing engine, but it has cured pinging on my Explorer many times over.
