in trying to eleminate a PO300, i am at the point of wanting to measure the resitance of the coil packs. in my manual, it tells what terminals to touch, but i dont even know how to set my eletrometer thing to measure resistance.
the manual says the limit is "Without 0 ohm or infinity maximum ohm" when terminal 1 and 2 are touched
when 1 and 3, and 2 and 3 are touched the limit says "Same as above" or "Without 0 ohm or infinity maximum ohm"
i am completly lost.....but i cant get the truck above 40, and if there is a hill, i will get a flashing CEL, (PO300) along with looks from other drivers passing me, lol .......ive replaced air and fuel filters, cleaned the egr, ran seafoam,(in a strong solution) in the gas, replaced fuel pressure regulator, cleaned and inspected the MAF, got the timing covers off right now, and everything lined right up. i also replaced the sparkplugs with ngk irdium. the truck is just running so sluggish
here is the pic of electormeter thing i got and im using.
on the ohm scale, (in grey) i have 20M, 200k, 20k, 2000,200, and an arrow pointing at a plus sign looking symbol.
i need to get out more, or trade up on some friends, cause everyone ive called around here dont have a clue. lol
