rb20det swap... i checked ecu for codes.. i think i read 56 or 57.. what are they? i can't find anything.

the other day for no reason.. my idle bounced up and down at 1,300 and 2,000... my engine miss-firerd... it ran way rich, smoking black,,, it wont rev smooth... one time i reved and bogged down at 6 grand and all the others wont even make it pass 4 grand unless i really floor it and play with the trottle..

i have already tried 3 other mafs sensor so yeah can't be that..

also i have unplugged soo mamy sensors.. i unplugged mafs, i unplugged, throttle, i unplugged the iacv and no change to nothing.. each one of those i unplugged it made no change.

WTF is wrong?

sounds like the tps isnt set right and the coolant temp sensor took a poo.

my coolant temp was leaking a little a bit the other day.. : (

will a ka coolant temp sensor work?

It should. During my swap I re-used a lot of sensors from my KA24E and it runs like a charm..minus the new upcoming issues.
