2004 SVT blew out spark plug took to Ford dealer who repaired with helicoil, road-tested everything fine.
Decided to change timing belt, pulleys ,tensioner and water pump. I mentioned SVT's could be finicky and included instruction sheet to try and help.
Went to pick up car... within 100 yards engine kicked light on and had about 1/2 power.
Back I go round 2. They double checked everything and mentioned Ford regional service rep helped them at the belt change as he happened to be there at the time.
They discovered and printed this analysis.
" Roadtest verify cust. concern performeec.test had cvode p1383 moniter pids pcm not changing timing perform pp. test hk test wiring akk ok at this time perform component test on sol. passed check for voltage drop on circuits ok need pcm as per pp. test. "
What are the odds the pcm failed during the belt change?
If the cam pulleys were off a bit would it not kick on a Timing advance retard code?
