last time when my cobalt did that it was because it was overheating. couple solutions is if this is the issues is that the fan doesnt kick in until the engine temps are over 223 degrees or so. i would either.

1. rewire the fan to another power source that provides constant current
2. trifecta tune that will allow the fan to stay on.

my fans are wire direct to a tago switch i turn them on befor the race.....

 

[cobalt123]

i found 2 bad fuses so i replace them . started last in the 6 lap heat finish 3. feature came out i pulled 6 car lenghts away from the pack... around lap 15 outa 20 my right axle broke, car never went into limp mode . also change to a cold air intake cus i found out the stock air setup was junk and leaking dust/air down the intake...

looks sweet but you got me stumped no idea why its engine power reduced

 

[lmzflame]

Well i change the throttle body sensor, and few more fuses. now im having a spindle prob, these aluminum spindle keeps breaking .in two weeks i broke 2 spindles and 2 axles, Do they make steel spindle ? also i have a stock motor but i wanna little more cuz i race against trucks ..... they seem to be bit more faster then me. I dont wanna use a turbo yet. so any ideas would help me alot . i just wanna finish one race befor the season ends.

dont know but i have had my car say power reduced before and i didnt know what the hell was going on . i check all the ground wires and cleaned up my battery ( little coke and a wire brush ) havent had the problem since . it was weird it didnt do it all the time and would do it some times after a long ride .......dont know but worth the shot

 

[lmzflame]

Guys i really need figure out why this car shutting down on me.

 

[Intmd83r]

you checked all the ground wires ?

 

[lmzflame]

Im going to change throttle positions sensor, yes all grounds are good . Can anyone find a steel steering knuckle . whats the best tires i can use for Dirt? im running Fusion Tires right now

 

[cobalt123]

your situation is completely outside my forte, all i can do is bump your thread

 

[lmzflame]

i change the throttle body and it hasent shut down on me yet..... but now the car keep breaking the spindle/steering knuckles .... i really need to find some steel ones or get some custom made .... need some ideas on this.... after 15 races i haven't finish one yet. ;(

Guys i really need figure out why this car shutting down on me.

It's gotta be something in the throttle body. Or add more grounds.
