1993 Saturn SL1 Bad Rocker Arms or Compression?

Used to just low tone click but recently gotten worse. Starts fine but when I start to back up slow it will start clicking under the hood. When done backing up out of driveway stops. At a stop sign or stop light on idle it will most of the time start clicking again but this time it will miss and the engine will shake. Has not stalled but I guess it could I don't know. When I start to move again stops. No other times it does it. Tune up is fairly new and coils and module is new. Belt is new and tenisoner is fine. Sounds like clicking is near the belt but it's possible it can echo there. Exhaust is fine.

I have someone telling me it's the compression and someone else tells me rocker arms or cam lifts. I search to get a price on rocker arms to see if worth to fix if they are bad but I don't see any, does this car even have rocker arms?

Prefer if saturntech to answer if available. Thanks.
