Question about 2001 Saturn SL
If the coils were bad, you would have more then that issue and does any check engine light show up on your dash. What kind of tune up did they do??? Wondering if they crossed the spark plug wires, if they did change that or if they just replaced the spark plug and damaged the spark plug wires when the spark plugs were replaced.
Thank you for using Fixya and keep me posted, you should have 2 coils in the 4 cylinder engine. But they should be still good if they were fine before you had them tune it up.

If it was working well before it went in and now it works badly I think there is something strange going on. Take it back and demand they go over everything for free to make sure they did not leave anything disconnected, from what you say it sounds like you have a vacuum leak on your intake manifold perhaps because a pipe has not been reconnected properly. If they refuse to make good then take the car somewhere else for a second opinion. In this day and age a 'tune up' is not required as the on-board computer takes care of everything and even reports on the faults. Ask them what sort of error cods are reported with coil failure (this is trick question since the coil is outside the ECU monitoring so no error code). A 'tune up' can mean a good opportunity for the unscrupulous to sabotage a vehicle to gain extra business. If you think for one moment these guys are on the make then take your business elsewhere.
