A list of all things that could make a L-Jet Jerky, now with ............Pics of my troubled head Options

[jsayre914]

I have a great daily driver. 1.8 L motor with L-jet injection, and it jerks like a son of a %^$%. It has all new vacume lines, none of wich are leaking (idles smooth at 900rpm) i have blocked off the deceleration valve. It was not letting the idle come back down fast enough for my taste. New jugs rings pistons etc. It has new plugs and wires. a new resistor pack and a newer duel relay. new alternator and new voltage regulator. Valves adjusted .006/ .008 perfectly with new valve cover gaskets. It has a new fuel pump and fuel filter, and many new wiring harness. Injectors were all cleaned and new screens put in. It runs up to 5K with no problems and runs strong to about 110mph on a flat. (IMG:style_emoticons/default/driving.gif)


Whe i accelerate easy it starts to jerk the whole way. If i try to run in 2nd or 3rd it jerks the whole time even at constant speed. sometimes i will seesaw the clutch just so i dont look to embarrising.

What is the list of things to check (i want to check everything) but i feel like i checked it all and then rechecked it (IMG:style_emoticons/default/confused24.gif)


one other problem probably related, i cant keep constant power to the fuel pump through the relay, it chokes off sometimes and dosnt want to come back (PITA) so i jumped the fuel pump lead to the + coil for now. (dont be mad) (IMG:style_emoticons/default/rolleyes.gif)
