okay...88' 4.0/ba-10/231
i get a surging when i start up cold (no high idle, right to 750 or so...then drop to 500...maybe 400 and back up, down and back up. but it drives just fine if you give it a little gas.
however when you go and get on it a bit....it has a dead spot where its laughs at you.
my friend drove it tonight and he said is seems like it's missing almost when you get on it (no stutter though)
so heres the things when you are drive easy (maybee 1/8-1/4 throttle its fine...drives and accelerates decent...get on it and its like nothing is hapening...like hte xj is dead almost...no pick up at all.
any help is appreciated...i thinks is the engine temp sensor (screwing with the injector timming), but i'm not sure because of hte throtle part of this equation...i think it might be the tps all fucked up (cleaned the tb with the sensor in, didn't know it was a no no)...i guess i can unplug that and see if its that.
then again it could be a vacume leak (but all seems ok).
the cap/rotor are new, wires are new, plugs look new.
and help is appreciated...thanks
