ok going to try this again
i am also posting this at the rangerstation.com


This has been doing this for about a month now
At idle and slow take off

Added 4 cans of dry gas in the last 2 weeks
Replaced plug wires because of sparks 5 days ago
Triple checked wires to plugs for correct connections
Replaced fuel filter 3 days ago

Ran a code scanner today after clearing a 116 and a mass airflow sensor code
Got no codes after 2 mile test drive
Also last night i pulled the battery connectors and the {ecm connector}, after the battery so no shorts to ecm

When i put code reader on ranger the temperture guage works when i run koer tests

Still runs rought at idle

I have about 60,000 miles on plugs so i am going to change soon but i pulled them and they are all getting spark from coils and they are tan to grey in uniform color {all plugs}

During the warmup before the testdrive my temperture gauge worked right for the first time in 7 years

I also am still playing with the number 4 plug wire on drivers side just to make sure it seated so i left it off during the warmup
After i hooked up the number 4 wire the temperture dropped down to where it was before

I sprayed carb cleaner and compressed air in the temp gauge connection in the motor compartment and the ecm connection { with battery diconnected}

I have alot of corrosion on alot of engine connection
and have been cleaning all that i have seen for last year

Another question? if i pull the vaccum line off of the egr canister should there be a lot of vaccum i dont feel anything from the cannister or the vaccum line

Still runs rough at idle but not when high revs
