Affected: 1989 FIREBIRD MODELS WITH 3.8L TURBOS
FIGURE 1:
Poor engine performance of 3.8L Turbos in 1989 20th Anniversary Trans Am models may be attributable to a water saturated air cleaner filter element.
In certain situations, water may follow the left fender flange to a hole (location A, Figure 1), drip onto snorkel-to-housing seam (location B, Figure 1) and seep into the air cleaner housing.
To correct the condition use the following procedures:
1. Seal the snorkel-to-housing assembly seam (location B, Figure 1) with RTV sealer or equivalent.
2. Drill 1/16" drain holes in the bottom of the lower air cleaner housing at locations indicated in Figure 1.
