I think it jumped time but the car still starts and every now and then it backfires through the intake. one morning I started blurpel and she sat there and idle was fine I let her warm up and then started for work I heard a loud pop/bang type noise and I thought oh boy she's done but she ran fine to work and after work no power and flashing engine light and she idles real rough any clue what is causing this thanks

    I doubt it jumped timing...but you have a misfire on cylinder one...possible ignition, or fuel issue...

    Thank you now I only have two areas to check instead of the multitude like the repair manuel states.
