I have a '87 GL fwd wagon with the Ea82 spfi and I was wondering what would cause it to run real smooth but be very sluggish between 10 and 25 mph? I mean you can put your foot to the floor but she feels like your not giving it anything....

Many Reasons could affect the Behaviour of the Engine, when Runnin' on Low RPM's, beside the Vehicle's Weight / HorsePower Ratio, Load, Kind of Road; I can Think on these "Easy Check & Fix" Ideas that Might Help:

• Bad Timing.
  
• Failing Advance at the Distribuitor.
  
• Clogged Cat and / or Muffler.
  
• Worn SparkPlugs.
  
• Low Octane Gasoline.
  

I Kindly Suggest to do a "Tune Up" Changin' Sparkplugs if they're Old and Check your Subie's Engine Actual Timing Degrees, it Should be Around 20º

Kind Regards.

Thanks I just had the timing belts replaced at the dealer but i do need to do a basic tuneup...Heres hopin that will fix the problem...

On the SPFI the ignition timing is supposed to be 20 DBTDC
