Book Excerpt: 1984-1988 Pontiac Fiero Repair Manual


The Pontiac Fiero is the first American-built mid-engine sports car. Although it uses many existing GM components from other vehicles, the Fiero combines these parts in innovative ways.

Moreover, one aspect of the Fiero's design that is shared with no other vehicle, American or foreign, is its "space frame" and chassis design with separate reinforced "Enduraflex" body panels.

Corrosion free exterior panels are bolted to the space frame, making them easily removable if repair or service is required.

Two engines are available in the Fiero. The base engine is a 2.5 liter four-cylinder, mated to either a five-speed manual or three-speed automatic transaxle.

In 1985, an optional 2.8 liter V6 engine, equipped with an automatic transaxle or a four-speed manual transaxle, was added to the line. In 1987, a five-speed manual transaxle became available as an option for the V6 engine.

Some 1987 and all 1988 2.5L engines are equipped with a force balancer. This assembly is attached to the engine block at the bottom under the crankshaft and extending into the oil pan. This engine requires a cartridge type oil filter.

THROTTLE VALVE (TV) CABLE - REMOVAL, INSTALLATION AND ADJUSTMENT (Refer to illustrations 5.3, 5.6 and 5.10)
  1. The throttle valve cable controls the transaxle line pressure and consequently the shift "feel" and timing, as well as the part throttle and detent downshifts.
  2. The TV cable is attached to the link at the throttle lever and bracket on the transaxle and to the throttle lever on the TBI.

  4. Disconnect the TV cable from the throttle body (see illustration).
  5. Pull up on the cable cover at the transaxle until the cable is visible. Remove the bolt securing the TV cable at the transaxle. Disconnect the cable from the transaxle rod.
  6. Disconnect the clip securing the TV cable at the valve cover.

    NOTE: Adjustment of the TV cable must be made by rotating the throttle lever at the throttle body. Do not use the accelerator pedal to rotate the throttle lever. The engine must be off during adjustment.

  8. The free movement of the TV cable can be checked by pulling the upper end of the cable. The cable should travel a short distance with light resistance due to the small coiled return spring.

    Pull the cable farther out to move the lever into contact with the plunger, thus compressing the heavier TV spring. When released, the cable should return to the closed position.
