having problems with my ka. its just been rebuilt 281 miles ago ran perfect for a few days.. then it went Rogue on me :wtf2: .. at this point in time it runs but idles like crap. it doesnt sound like its missing or any thing but the second i touch the gas it will bog its self out and die.. also if i leave it alone while its idleing it will eventually cut off..
so far i have replaced the dizzy, coil, ignitor chip, double checked my timing, checked fuel pressure and to see if the injectors where spraying, i replaced the tps, the maf and gone thru my wiring. i cant seem to figure it out.. any ideas???? dizzy plug wires where cut by the previous owner but resoldered and ran fine before i blew the motor.. all the wires are still attached..
also im only throwing code 55 (no malfunction)
thanks

sounds like an injector problem..leaky o-rings or bad injectors..test the injectors with an OHMS tester.

My first thoughts turn to the fuel pump is on it's way out. Second thought is a vacuum leak. Could have had something come loose after the first couple days.
