1999 Isuzu Trooper Problems

Engine -- Verified

A ticking noise may be noted from the engine valve train area. This is commonly caused by varnish build up in the hydraulic lash adjusters (HLA). Our technicians tell us that using Mobil 1 synthetic oil has been successful in cleaning the varnish deposits and quieting the lifter noise.

Engine -- Verified

A rough idle may develop which may or may not cause the Check Engine Light to come on. This issue is commonly caused by a failed intake manifold gasket which will require replacement.

Electrical & Lights -- Verified

The fuel level sensor may fail causing erratic operation of the fuel gauge. Our technicians tell us that replacement of the failed sensor is necessary to correct this concern.
