well, i ported my manifold, took out my 6 port system in hopes of fixing my 6000 rpm hesitation, no luck, all im left with now is the fuel filter and ignition components, ive already ran extra grounds to the block, and to the leading coil, i need to do the MAP and ECU still. what do you think?? from 6000 up it doesnt pull, it will go, but it doesnt pull at all, i thinking its spark now

 

Uh, did you check your TPS?



-Ted

 

yea, replaced the TPS with a working one, didnt help

 

Can you tell me what the MAX resistance value is on the TPS?



-Ted

 

max is between 6.12-6.27

 

Finger sure looks like ignition misfire or fuel filter problem.&nbsp ever pulled the spark plugs after a hard run?&nbsp If it's a fuel problem, the plugs will come out white.&nbsp If it's an ignition misfire, the plugs will come out black...

Whats the timing set at?
