    Rough idle and lights flickering..any ideas?

    I just got back from firestone, they replaced my heater core/evaporator system, no more leaks, nbo more smoke, and no more breathing in coolant gas

    But as i stopped at the first stoplight down the road, I realized that the idle was EXTREMELY rough, seatbelts were shaking, mirrors were shaking, just wow, i was amazed at how rough the idle was. So i pulled in my driveway, and sat for a few minutes. RPM's at idle were bouncing a little, and i noticed a slight flicker in my headlights, dashlights, and inside lights. Does anyone have ANY idea what this could be caused from?

    I didnt think replaceing the heater core could have effected anything with the RPM's / idle, but im not sure.

    What do you guys think?

    Re: Rough idle and lights flickering..any ideas?

    back when my idle was doing that, and the lights too, i ended up killing my battery because my electrical wasnt enough to keep up with the system

    the car would even shut off, after this had been going on a while

    also someone told me it couldve been my alt but it ended up being my battery

    thought this might help

    if you have stock electrical, the new heating system could be causing a drain of your electrical system that didn't happen before. other than that i have no idea

    maybe they pulled a spark plug wire off inadvertently. that wouldn't really explain flickering though.

    My Eclipse will act like that for the first 100 miles after the battery is disconnected.

    It resets the car's ECU to the baseline, and it takes some driving for it to relearn the correct sensor settings, after that it runs fine.

    I might believe its your computer readjusting. give it a little time, and if it hasnt fixed itself, take it back.

    The thing about that is, if i wait too long, I'm sure they will come up with some lame excuse about me doing something to it.

    You're right, a lot of shops will. So take it back asap, and let them figure out what it is. If the say it will adjust itself, and that you need to drive it for a while, then at least you have proof that the problem happened immediately following their service. Then, if it doesn't correct within an acceptable time frame, take it back and demand that they fix whatever they did.

    Could it possibly be my alternator? Im not sure if it could be, because it ran fine this morning when i took it to the shop. (aside the fact that coolant fimes were pouring out of the air vents, lol)

    Re: Rough idle and lights flickering..any ideas?

    just go back tomorrow. there really is no way to just diagnose it over the web.

    the heater core is in the dash, so i wouldnt be surprised if they pinched some wiring while pieceing it back together. if they had disconnected the battery and the ECU reset it self, then that can cause a problem for quite a while before it relearns all the info it needs. or it could be a coincidence, that something else went out during this time.

    its as simple as that. you have SO much leverage in this situation in the eyes of the law. if you end up having problems with them not wanting to take the blame, its as simple as a call to the BAR (beureu of automotive repair).

    its making me wonder though why you didnt notice it as soon as you started up the car when you were leaving and said something then (well i guess you kinda did)
