#305996 i have a 92 si hatch with a pmr swap. obd1 gsr bottom with obd2 b16a2 head. everything is set up obd1 tho. running a p28 ecu. the previous owner said it was tuned but i cant prove it. thought maybe the tune just went to sh*t. but i dont know for sure.

i have a hiccup under 3k when i give it a good bit of gas. if i accelerate slowly tho its not there. and doesnt do it right away. takes a min before it starts. its driving me crazy. had it for atleast 6 months now.

but if it starts to hiccup i can turn the ignition off and then back on and it wont do it for maybe 2 or three mins. or like the first 2 times i come to a stop and start again. but it always come back.

ive change out the dizzy, added the IAT sensor back on (left off when privious owner did the swap) , swapped a few iacv, check all my wiring for anything loose or corroded. no luck tho.. hoping someone has had this problem before because i need help!!
