h22 help
Hey guys need some help really stumped. 92 prelude, My setup now is an jdm h22a before I had an h23a1. Obd1 dizzy w/ enternal coil. Obd1 h22a fuel injectors. P28 ecu from phearable. Vtec kit from axid works. Egr valvue from h23a1. Well start idles fine without map sensor pluged in. But when map sensor pluged in car seems to shake and idle fluctuates. Im getting carbon on my sparkplugs but im going to double check my timing today. All vacuum lines have been triple check including all sensors tps, egr, o2, iavc. I tried to use the map on firewall same result. Tried to use map on throttle body same thing. Confused.. anyone help me out?

Re: h22 help
Im getting carbon inside combustion camber and plugs are getting dry carbon.. and when I plug in map sensor car idle fluctuates and car shakes. I tried 3 different map sensors already 1 of them is brand new. Car idles fine without map sensor so I know its that one. But the thing im trying to figure out is why

I've never heard of a situation where a map sensor was bad and it didn't throw a code.
Just because you unplug the map sensor and your car appears to idle better doesn't mean the map sensor is bad. Not really sure why people seem to think this day in and day out here.
Plug in a stock h22 ecu. See how it runs and check for codes. Then go from there. You never ever start off with a chipped ecu.
