problem #4

Feb 102014


  • Automatic transmission
  • 200,000 miles


I have problems with my car dying as I am driving it, I lose all power even at 50 miles a hour and then you cant start back till it cools down, this all started after I had a water leak fixed in the top of engine, cost me over 700, he gave me car back and it sounded so bad had no power, he said maybe busted head I was yelling noway it sounded so quiet when I brought in,,,then he claims he had left a connector off and that caused it, then it started dying as I was driving down road every day at least once but would start back, the last time it did this it wouldn't start back backfired over and over when trying to start, I had noticed the battery gauge moving while driving to the mechanic said my radiator had no water and no antifreeze,my gauge hasn't worked since he fixed the water leak, but I didn't believe that would cause it to act like this, I paid another 360 well now I am out all this money and my car still isn't fixed I knew it wasn't the radiator causing this !!!

My car 2000 Pontiac Bonneville will stall while driving around 1200 rpm and when i start the engine turns but it won't fire up most of the time when i pump the gas pedal it started.Yesterday 2nd of feb 2011 after the snow storm i can not get the car started until the battery drained i had it boosted but still the engine just turns and sometimes it hesitates and almost going to start it seem like this is electrical problem.

This car is wacked, I've been up against some tuff diagnostics but this one takes the cake. New computer, new security module, new fuel pump, key reprograms, it still will stall while driving. Sometimes it will restart fine, other times it just stumbles. Any help !!!!
