^ Engine stall during warm-up
^ Rough idle
^ Sudden rpm rise when A/C is turned on
^ Increased throttle effort from idle
^ Purge control valve ticking noise at idle
^ Long restart after stall in cold ambient temperatures
^ On M/T models, surge under light throttle or sudden rpm drop after clutch release
Models produced before 6/16/94 (VIN SE027236)
Models produced after 6/16/94 (VIN SE027236)
All 1995 M/T 420A Models
