Greetings,

I have a 2000 Ford F150 with the bi-fuel package. The truck has been very good to me over the last 4 years. Very recently, the engine started to have a hesitation issue with accellerating from a stand still when I was running on CNG. Brought it to the dealership and they said I needed a tuneup.

Here is what the tech said at the dealership.

SCOPE EEC TEST ALT FUEL TEST MISSFIRES ON CYLINDERS 2,5,6,7.
3 NEEDS TUNE UP AND CLEAN AND RESEAL.

The cost for this tune up was estimated at $1,500. This includes 12 hours of labor at 97.50 an hour. To say the least I taken back by this cost.

What my question is will this fix my acceleration problem or are they trying to make a buck. The truck runs fine on regular fuel but since I primarly use CNG they said that what cause the plugs to go bad. I would run on CNG for 60 days then run one full tank of regular. This is what is recommended by ford. By the way this CNG vehicle was built by Ford in Canada.

Any thoughts? idea, suggestions, all will be entertaining I'm sure

have you tryed a tune up yourself,plugs and filters.
if you post this in engines you might get more replys

 

Thanks for the sugggestion. I will post in the engine section.

I have thought about doing the tune up myself however the CNG regulator and other components are covering the entire side of the engine. These would have to be removed. No room at all to access the plugs. Thats why the dealer wants to charge $900 for 12 hours worth of labor.
