93 CIVIC WITH H22A4 swap boggs after 4-5k rpm
it drives fine under 3k rpm, idle fine
so far i clean out the map sensor, i wired up the resister box, clean the injectors, gave it a tune up, still boggs, NO CEL
vtec comes ono but when it kick on it goes slower i cant pass 5k, it'll bogg real nasty

help please
thanks in advance

did u get it a tune up? i my car was doing that also, i change the spark plugs an it ran a little bit better

Do you know if your Engin was OBD2 or OBD1? the OBD2 does not need a resistor box and could cause your car to run like $hit. I ran into this problem when I did my firs H swap. Obd1 have the gray clips and the obd2 have the black clips.

yes i gave it a full tune up...i change my plugs ran alot better i was able to pass 5 then it started bogging after 6ish..the motor is obd2 in a obd1 car i changed the injectors to obd1 h22 injectors...IDK wat the problem is..irritate the hell outta me..i did every thing i could..an think of...idk what the problem is

i had a similar problem on my old eg it turned out to be the ecu i wasn't getting any cels or anything but once i changed the ecu, tps and intake temperature sensor problem solved.

H22AFerio

Yeah I would swap out the ecu see if that solves the problem.

i rewired my resister box. same problem...i changed my ecu to a p72 problem is slight worse...change to a p13 problem went real bad...chipped p28 does good but boggs after 5500..

i think ima try another h22 throttle body..an see if that does a diff with a diff tps..other than that what else can it be

EJ-1

bump...ima try an use a diff TPS sensor...an change my resister box..

EJ-1

i checked the timing to see it was off..that was good...so idk where else to look

im thinking its your ignition side, spark plugs, wires, dizzy

EJ-1

^ u are correct..tried another tps..problem still exist...rewired the whole injectors..and change the whole dizzy problem went away....damn the h22 was faster then my high comp b20..an gsr...
