injectors or trans?
Author Last Post

Well I threw injectors at it & now it works much, much better - also saw plugs, 8 had been running too rich, cleaned and reinstalled (plugs are only one year old). Still idle seems to roll i.e has a lope. Looking at doing coils (two have been changed in last 5 years) & wires.... Any other ideas?

1993 Allante, no light or relevant codes, roughness with very occasional miss at idle which improves with injection cleaner (Techtron or Liquid Molly) and goes away completely after hi-speed highway trip of 250 miles or so but then comes back after some days of city driving. However, there is also a stutter/judder at 2000rpm in 4th on slight acceleration and on a slight rise (going up an overpass). (Has had tuneup plugs/wires/coils to fix hard miss w/ trans code & codes a year ago). Car runs strong on hard acceleration. I'm stumped and don't just want to throw injectors at it. What is this I hear about replacing trans solenoids?
