What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 1990 Isuzu Impulse, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Driver assistance

From owner reports, verbatim
CONSTANT STALLING AND/OR HIGH REVVING OF ENGINE. STALLING USUALLY OCCURS WHEN COMMING OUT OF GEAR AND IDLE GOES DOWN TO 500RPMS OR LOWER AND STALLS OUT. AFTER SOME RESEARCH I HAVE FOUND THE PROBLEM TO BE AN ACKNOWLEDGED ECU PROBLEM THAT SHOULD BE REPLACED AND ISUZU NEVER DID.*AK
ENGINE IDLE JUMPS ABOVE 3000 RPM AFTER PULLING TO A STOP. WILL OCCASIONALLY RETURN TO NORMAL AFTER SEVERAL MINUTES. CAR RACES AND ACCELERATES UNCONTROLLABLY WITH CLUTCH ENGAGED UNTIL IDLE SPEED RETURNS TO NORMAL. IAC AND STICKY THROTTLE CABLE HAVE BEEN RULED OUT. PROBLEM APPEARS TO BE RELATED TO THE DELCO ECU, AS EXPERIENCED BY MANY OWNERS OF VEHICLES WITH 1.6 AND 1.8 LITER FI 4XE1 AND 4XF1 ENGINES. MANUFACTURER HAS REFUSED TO ACKNOWLEDGE THIS PROBLEM.
