Ok i Am going Crazy here. ive posted this on The Rx7 club and no Help there. I was going 70 down the freeway and It lost Half of the Power in the engine. Its a 1987 N/A 5 Speed. i thought it was My Bad Alt so I replaced it. no dice. one rotor was Lean one was Rich so i replaced the Primary Injectors with New Delphi's stock resistance's and CC's. basically a Oem replacement. Have spark and fuel getting evenly to each rotor. but it wont start. If i Do get it to start it runs like **** and dies after about 5 min of runtime then Refuses to start up again. Please Help

could be the MAF your right. i would get some cleaner(only for MAF sensors) and spray it out (ONLY THE MAF STUFF) i assume no MSD box? then i would check all the grounds and clean them up. i allways say grounds couse it seems like i allways run into grounding problems. i am allways cleaning and checking the grounds and it still just bit me in the *** a few weeks ago.
