iron duke... very retarded (literally)
2.5L Iron duke... 8.3 or so compression (electric fan conversion, 165degree thermostat, but all stock)
Reman head, new plugs, wires, dist cap and rotor.
88 Chevy S-10, 5spd... TBI
ok well, my head gasket blew, and i ended up swapping on a FWD head, and it pinged like crazy and ran like crap... I havent touched anything timing related.
Anyways... now... about 5 months after the head swap, ive been noticing it hesitating, uasually in 3rd 4th or 5th, when i give it gas, usually around 2500 and up.
no matter what gas i run, it always seems to do it.. it just hesitates and hesitates for about 2 or 3 seconds when i give it, even moderate gas.
I checked my timing today, for the first time in a while, and its reading about -15 degrees at idle, and i didnt check for when it kicks it up.
Well i have never done timing, so thats why im posting on here before i go screw something up. I am guessing i want to set it up around 0 and then see where to go from there. More power is always a plus, but never easily obtained on my engine.
I just posted on here, to make sure it IS the problem, and im not going to make anything worse, or anything i should know before i follow the instructions under the hood... aka ground this, and so on so forth.... concidering it is EFI.
Any help is appriciated.
Would Negitive Timing (thats numbers BTDC right?) make me miss? i thought more positive numbers would lead to ping... maybe it works both ways
Thank you everyone!
