AIR FLOW METER NO START Ive had a problem with my rx7,i cleaned my K&N air filter and put it back on, i turn the key and the moter just spins no spark the tach dosent move at all like it usually does and no smoke coming out of the mufflers so i know its not flooded, it seems that the ingnition isn't working i did a post a week ago and tried all suggestions none worked, as i was taking things apart and putting them back together i got in the car and tried to start it, the car started and then stalled i was happy for a sec i got out the car and saw that the MAF was disconnected i must of forgot to put it back on, anyway i put it back on and nothing now the tach doesent move like it does with the MAF disconnected it off i can't explain it? does anyone know whats going on does the MAF effect ignition at all????????
