Hi,
first, I know this subject as been covered but cant find any answer !!!!no conclusion too almost all the threads about it !!!

my obd1 h22 got a little hesitation,sputting problem!!!!

I got almost NO torque between 2000 and 4500-5000 rpm !!!!
its starts great but at 2000-3000 its starts hesitating like if the TB wasnt opening .

If I hold the gas on the highway at 4000(example) after a little time ,its starts sputtering alot !!!If I hold my gas pedal on neutral at 3000(example)
the rpm drop to 2000 and go up again .even if my feet doesnt move from the gas pedal !!!!

I've change IACV,Tps,sparkplug,wire,distributor(rebuild),cap and rotor,walbro fuel pump,honda fuel filter .

I got another IACV from a b18c1 and it runs better with it ,but still not perfect!!!

I also got obd2 injector without the resistor box(bought it like that)

the ecu is a p28 chipped with crome.

If you need other info just telll me ....I dont know where to look ....

bad timing ? bad map sensor? ....if I dont find the problem i will sell it !!! everyone in Quebec that say they are h22 specialist cant find my problem!!!!!
compression is perfect also .....please help me :(
