97 ford tarus gl backfires in the morning started shuddering in gear engine light went from on to blinking and the rpm jumps down hard in between gears going up into1- 2 but not drive- any ideasalaska?


If the check engine light is flashing, it's telling you that there is an IMPORTANT computer code that you need to read RIGHT AWAY!!! You can get a code scanner at most auto parts retailers. Some let you borrow one and will even help you figure out what it all means. But you can borrow, rent or buy a code scanner at your favorite auto parts retailers.

Seriously... if it's flashing, get on it RIGHT NOW!
I wonder if the vehicle speed sensor might be involved(?)

Sure would be interesting to have heard the outcome / fix for this one...
