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 STALLING FOR NO REASON WITH NO TROUBLE CODES. THESE SYMPTOMS WILL OFTEN ONLY OCCUR IN WARMER WEATHER AS THE METAL CIRCUITS OF THE CIRCUIT BOARD SEEM MOST VULNERABLE TO SHORT CIRCUITS AT SOLDER CRACKS WHEN THE TEMPERATURE WITHIN THE CAR IS ABOVE 80 DEGREES FAHRENHEIT. IN TEMPERATE CLIMATES, THE SYMPTOMS MAY FIRST SHOW THEMSELVES AS SOON AS THE WEATHER WARMS AND PLAGUE THE OWNER ALL SUMMER LONG, ONLY TO SUBSIDE IN THE FALL WITH THE COOLER WEATHER AND THEN REAPPEAR THE NEXT SPRING.
AS THE WEATHER IS GETTING WARMER THE ENGINE REVS AND DROPS UNCONTROLLABLY. THE CAR ALSO STALLS AT ANY SPEED. I HAVE HAD IT EVEN STALL ON THE HIGHWAY. I HEAR THIS IS A COMMON PROBLEM ON THIS PARTICULAR TYPE OF ECM UNIT, PLEASE CHECK INTO THIS FOR ME. IF I HADN'T TAKEN A DEFENSIVE DRIVING COURSE I COULD BE DEAD RIGHT NOW. *AK
ECU HAS ERRATIC PROBLEM. WILL PUT THE CAR INTO HIGH IDLE AT ANY GIVEN SPEED AND WILL NOT RESET UNLESS CAR IS TURNED OFF AND RESTARTED. REPLACE ACCELERATOR CABLE AND RESEATED ECM SEVERAL TIMES TO NO AVAIL. TRY RESETTING THE ECM TO GET THE CAR OFF OF HIGH IDLE WHILE YOU ARE IN TRAFFIC. *AK

THE NUMBER OF FAILURES IS RELATIVE TO THE NUMBER OF TIMES THE CAR SURGES ON ME PER WEEK, BUT NOT HOW MANY TIME THE ACTUAL EQUIPMENT HAS HAD TO BE REPLACED.
I HAVE HAD THIS PROBLEM ONE TOO MANY TIMES, AND IT IS STARTING TO GET ANNOYING. I CAN'T AFFORD TO BUY ANOTHER CAR RIGHT NOW AND I WOULD'NT WANT ANYONE ELSE TO HAVE THIS PROBLEM WITH A CAR. IT'S VERY DANGEROUS. MY CAR CAN TAKE OFF AT ANY TIME IT WANTS TO. IT ALMOST MADE ME GET IN AN ACCIDENT IN A TRAFFIC JAM. THE DEALER WON'T COV…
