Re: Sniper throttle linkage extension (homemade w/pics)
Does the TPS reach 100% if you manually open the throttle blades, right at the throttle body?
You may have a situation like I had on my present car, which was the steel rod that the gas pedal attaches to, and that pivots on the floorboard, was slightly bent, and no matter what, was not allowing the full pedal travel....basically it was "bottoming out" on the carpet, before the throttle blade was fully open....worth a look.
Also, one of my buddy's simply had the wrong cable...it worked fine on his Holley carb, but didn't have enough pull on the EFI throttle body. I ordered him a new cable, from Rock Auto, and it had 2 attachment points for the gas pedal end of the cable.
