|
Known Issues
|
Fuel System Reliability:
|
Bosch CIS-E can be sensitive to vacuum leaks; distributor rebuilds or seal replacements may be needed over time.
|
Electrical System:
|
Aging wiring harnesses, particularly grounds, and connector issues can lead to intermittent faults.
|
Suspension Bushings:
|
Worn suspension bushings (control arms, sway bars) are common due to age and mileage, impacting ride and handling.
|
Climate Control:
|
HVAC blower motor resistors, vacuum actuators for blend doors, and AC compressor clutch failures can occur.
