Single Cam S13 Help!!!!

[89Hatch240sx]

ok so i dont wanna dump shit ton of money just to tune this fucking piece of shit up...

it was running fine until a few weeks ago... now i start it up and it sounds like a Subaru WRX.... when i accelerate it feels like i have 35 hp and takes me forever to hit the speed limit...

while driving i willbe doing 55 and it will tug and and lose power consistantly...

idk wtf the prob is... sometimes it will idle so bad it will just die on me... ive replaced the Rotor and cleaned the cap really good... the plugs dont seem bad.... and spark plugs look ok... and it still runs like fucking shit...

im turning to you guys now... any suggestions? cause im returning the rotor and getting my money back... lmk if you have any suggestions... i cant afford for this car to take a shit on me.

you drop at least one cylinder. remove one spark plug wire or injector connector at a time. the idle should drop. if it does not that cylinder is bad. do this for all the cylinders. then check for spark, fuel and compression in that cylinder

Maf!

if it sounds like a subie its more than likely a bad injector or fuel pump

bad injector or bad spark to that cylinder could be cable or spark plug if its electrical
