THIS IS CONCERNING THE VARYING IDLE SPEED PROBLEMS ON THE STORM THAT WAS REPAIRED BY ISUZU/GM UNDER WARRANTY, BUT DOES NOT COVER VEHICLES OUT OF WARRANTY. MY CAR'S IDLE SPEED VARIES AND SURGES, RESULTING IN STALLS AND OCCASIONAL JERKY TAKEOFFS.

AC DELCO USED A INSULATIVE SPRAY ON THE CIRCUIT BOARDS IN THESE ECUS/COMPUTERS WHICH SHRINKS OVER TIME WHEN EXPOSED TO WARM AND COOL TEMPERATURE CONDITIONS, SUCH AS THE NORMAL CONDITIONS THAT AN AUTOMOBILE IS SUBJECTED TO. THE SHRINKING INSULATIVE SPRAY CONTRACTS AND PULLS THE ELECTRONIC COMPONENTS FROM THE CIRCUIT BOARD, BREAKING SOLDER CONNECTIONS AND CAUSING SHORTS. THE SYMPTOMS OF THIS FAULT ARE MOST NOTABLY ERRATIC IDLE, IDLE REVVING AND DROPPING, IDLE DIPPING OFTEN WITH ENGINE DYING, IDLE HANGING HIGH ABOVE 2,000 RPM, AND ENGINE DYING OR …

THE 1990 GEO STORM (AUTO) WILL NOT ONLY STALL, BUT IS STARTING TO ACCELERATE UNINTENTIONALLY. THE CAR ALSO SEEMS TO STALL IN RELATIVLY TIGHT TURNS. MY MAIN PROBLEM IS THE HESITATION AND SURGING/ACCELERATION. I HAVE HEARD THROUGH INTERNET NEWS GROUPS THAT THEIR IS A DEFECTIVE ECM COMPONENT ON THIS CAR AND THAT THIS DEFECT WAS COMMUNICATED TO CHEVY/GEO DEALERS THROUGH ITS TECHNICAL LITERATURE. SO FAR, I AM SPENDING HUNDREDS OF DOLLARS ON REPAIRS THAT WILL NOT SOLVE THE PROBLEM. IF THE DEALERS KNOW ABOUT THE DEFECTIVE ECM, WHAT KIND OF RECOUR…

Emerging complaint spikes

Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.

This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.

No complete months meet the spike thresholds for this selection.

Equal-age model-year comparison

Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.
