Ok first off I have a Ms1 v3 board with internal vb921's running the coils and MSnse code 029 (Im pretty sure on that) I have everthing up and running getting a good hot spark and the car starts and idles like stock AF ratio is a little richer than I would like but it dosnt seem to like 14:5-15 vary well. My problem is that under slight acceleration to mid acceleration I get an intermitant miss Im pretty sure its on 2 cyl and that it is ignition doing it not fuel. Also when just free reving this miss is slightly noticeable its just oh so slight though. Also this is a come and go thing somtimes it will do it other times noda. Under full load its completely gone and at idle its not there either. I have tried changing coil packs, Plug wires, cam angle sensor (mitsu 1st gen) I ran a larger power wire to the coil pack, better ground straps, ran a larger power wire to the MS and grounded it better. Everything I can think of without going internal on the MS. I have noticied when runnign that 1 of my vb921's gets conciderabley hotter than the other. Is it possible that one is slightly burned up??? I have a mitsu ignition transistor on the way and will be doing away with the igntiors but Im unsure 100% that it will work. I was wondering if anyone else might have an opinion??? PLEASE HELP!!!

try swapping the hot vb921 out and make sure its cooling itself properly... and make sure your dwell isnt too high... ;) im mxmang on aim and boredstoonguy on yahoo mxmang@hotmail.com if you need to reach me
