the car took a crap on me on the highway. i had no spark. i replaced the pick-up coil and it started right up and ran for awhile. then i took it on a test run and it got to my destination, but started to sputter as i pulled in. the car wouldn't start again when i came out to leave. i lost spark. i got it to start and run again but nervous about touching it right now. it'll run and drive but very sluggish. any ideas???

 

Fuel injectors?
