i tryed the tps that didn't help the manual say under the trouble shooting that it might be a loose connection at the distrubtor, coil, or alternator or a vacuum leak but checked the connections and looked for vacuum leaks but didn't find any thing I'm running out of ideas I'm getting frustrated at this build the motor went in about 4 months ago and i just got it to start but it wont stay running I'm about to take it to the dealer and have them fix it
