The 1988 model year

Overview

A near-pure carryover of the 1987 aero car. The 225-hp 5.0 and the 2.3 four returned essentially unchanged. The notable under-the-hood point: most 1988 5.0s used speed-density engine management, but California-market cars adopted the mass-air system a year early. (Horsepower figures are SAE net.)

Year over year

What changed

  • Essentially a carryover from 1987.
  • California 5.0s switched to mass-air metering a year ahead of the rest of the country (still speed-density elsewhere).
  • The T-top option was discontinued during the year.

Worth knowing

Notable

  • A clean carryover year; the 5.0 LX bargain continued.

Living with it

Reliability & ownership notes

  • Same robust 225-hp E7TE 5.0 as 1987 — strong and well-supported.
  • On a 1988 5.0, confirm speed-density vs mass-air (California cars differ) — it matters for tuning.
  • Inspect for Fox-body rust.
