Hey Ya'll,,Mother nature was kind today and blessed me with 55* sunny weather.
Tested the
CSI, PCV valve, compression test: 160,150, 155, 150, 160, & 155 PSI.
Since I had to remove the plugs for comdpression test,,, Cleaned them and reset the gap.
Who'd of thunk that cleanning and gapping would fix my problem?
Bosch doubled platinum plugs must be sensitive? I put them in with the fresh motor 10 years and 200 thousand miles ago,,,
Guess I'll need to check the plugs every couple hundred dthousand miles? LOL, ROFL }O
Only 330,268,996 miles on it now,, Wonder If I can get to a million like the Televison commercials in the 70's?
Have a great day!!
