intermittent starting issue 93 300CE
I am having troubles with my car starting consistently.
Sometimes the motor will crank over and not start, it will sputter mildly (kinda like small caughs) and I will have to floor the gas pedal (its EFI , WTH?) After about 10 - 15 seconds of having the pedal floored, it caugh faster and faster until it starts up and revs out. If I do not floor the gas pedal, the motor
simply will not start.
Ther are no check engine lights to aid in diagnosing other than a upshift delay and also a have no check engine lights currently but I just cleared a code 21 and code 25 that have not come back on in a days worth of driving
The codes are
25 Upshift Delay
21 Purge switchover valve circuit open or circuit short
I did some research on both of these codes, they didnt look like the bad guys....
Thanks for reading

I failed to mention that the intermittent issue is that sometimes, the motor will fire right up. Having warmed up the car or driven for a long time does not seem to be a factor, it so far appears to be random.
