i bought my 90 coupe with a 93 ka24de in it just to mess around with as a fun car. not my daily driver. Well since ive had it the car has had one main problem. As you drive in any gear it pulls nicely up to about 3200rpm then just falls flat on its face and has NO POWER at all. Still revs, but makes a ton of noise and goes nowhere. Also the car will not idle lower than like 1200 even with the idle screw all the way in!! also coming to a stop it will almost die unless i blip the trottle, then the idle comes up to 1200 again. I have since changed/replaced/checked these things
changed maf
changed ecu
No ecu codes
changed plugs
changed wires
changed cap
changed rotor
91 DOHC cams
new upper chain
fuel filter
fuel pump
injectors
Timed at 20 degrees
the only thing i have left i could possibly think it could be is a HUGE air leak, my CAS, or knock sensor or lower timing chain?.....idk how it could be my CAS or knock sensor cuz im not gettin any codes for them. what it feels like to drive is pulls hard to 3200 then feels like someone just backed out like 20 degrees of timing!!!
i am about to buy a new motor, but i dont think this one is bad!! compression is good still 170 across the board
SOMEONE HELP PLZ!!!
