things i have done so far and no luck yet. Why?

[90SXSE KA24ET DREAMS]

Still can't get my car to start up right, idle right, or run right, or anything.

things i have done..

new plugschanged all the relays in the relay box under the hoodno vacuum leaks what so everchecked timing- that's in checkcleaned out the idle air control valvecleaned the o2 sensor off with carbontry re-adjusting the idle screw a million times both ways, no luckmafs is brand freaking newair intake temp sensor is brand freaking newInjectors did leak fuel when i first got motor swapped, but i have changed the injectors and problem was fixed, and then my car was running good after that for a week.I checked the fuel pump, i hear it workingI have checked spark - i got a good solid spark on everything.I tried a different coilI cleaned out the throttle bodyall the grounds are tight, ecu plug is not loosetonight i have checked for codes 20 times and all it throw is code 55, which yeah means nothing is wrong, bull ****!!! the comptuer lies!i have checked every plugI have even open up the ecu cover to see and smell if anything had a burnt smell and nothing.I have checked the fuel filter lines to feel for preasue in the lines and there was preasue.

so everyone please help i have done and checked over everything!

all my car does is sometimes when i start the idle goes up 2,500rpm and sometimes 3,000rpm and it'll drop really fast and stall, and then other times it won't even do anything, and some times it runs up to 900pm and feel rough for like a second and then it stalls.

I tried keeping my foot on the gas to keep the rpms up but that doesn't even keep it from stalling out.

So i also thought my throttle is sticking.... checked it all out and NOPE it was fine.

Does anyone have an idea what is wrong with it and what is else left to check?

i have done everything in the list!!!

engine has 86k mileage, ka24e.

Maybe check the TPS sensor... I know when mine wasn't plugged in the RPMs would stay high when I revved it. Also you mentioned the fuel pump, did you stick a gauge on there and make sure you're getting enough pressure?

Just a couple ideas.

my tps is plugged in tho. confussed. : (

also today now.. tried 3 idle air control valves's and nothing

thennn i tried a different fuel pump and still nothing! and both pumps are working i hear them.

So, we can't tell whether it is starving for fuel or the spark is quitting. It is one of the two. What I have done in the past, to detect if the spark is there or not, is to connect one of the induction type timing lites onto one of the sparkplug wires, and keep the trigger pulled while the engine does its' thing. While the engine is running, the lite is flashing. If the engine stalls and the timing lite flashes until the engines grinds to a halt, you know you are starving for fuel. If the lite quits and the engine dies, you know it is an electrical problem. A quick diagnosis tool! It won't tell you exactly is causing the problem, but will steer you in the right direction.

Maybe time for a mechanic to look at it before you spend any more money on new parts?
