Hello . . . fellow tuners . . .

Today 2 of those lights went on my 97
81.000 miles. Well, I disconected bat cables.
First time check engine light went off...
Second turn, put back, IAT,( intake air temperature fuel-mod ),.,.to
one of the censor wires..result some power gain
probably see little worse gas milege...

Got 91octane car felt fine going home...Weird but happy to test performance
gain tomoroy. ( hope no mo check light's )
