any ideas i got a 93 mazda twin turbo the car has a few upgrades but still kinda factory set up the car starts up fine but after 15 mins when it warms up. The car turns the check engine light on and the idling turns irratiacally like if a vacumn hose has just popped off .So i guess when u try to rev it up the car starts missing, it wont make boost or properly rev up. So some people tell me that the car falls in safe mode when this occurs,i want to diagnose the check engine light but i dont know how to diagnose the car or were to look for codes so any help will sure be apperciated !!!!thanks
