I OWN A 1997 CHEV. S-10 ZR-2 WITH A 4.3 V-6 (85K MILES). FOR THE LAST
3 YEARS OR MORE I HAVE NOTICED A PROBLEM WITH HESITATION AT LOWER
SPEEDS UPON LIGHT ACCELLERATION. THE PROBLEM SEEMS TO OCCUR MORE WHEN
IT IS COLD OUTSIDE (LIVE IN MICHIGAN) AND WHEN THE WEATHER IS
DAMP/RAINY/FOGGY. THE PROBLEM ALSO SEEMS TO GO AWAY SLIGHTLY WHEN THE
TRUCK HAS WARMED UP. MORE RECENTLY THE COIL WENT OUT, I THOUGHT
REPLACING IT WOULD FIX THE PROBLEM I HAVE, ONLY NOW THE "SERVICE
ENGINE SOON" LIGHT OCASSIONLY COMES ON. TRIED DIAGNOSIING IT WITH A
COMPUTER TO NO AVAIL. I BELIEVE IT IS SOME SORT OF SENSOR PROBLEM,
WHICH ONE IS BEYOND ME, AND DON?T WANT TO SPEND A FORTUNE HAVING A GM
DEALER FIX ONLY TO FIND OUT IT WAS A $50 PART. ANY IDEAS? NEW FUEL
FILTER AND CAT. CONVERTER IS OK.

Relative to the "Service Engine Soon" light, I had the same problem with my
'95 C1500 (4.3 liter). No hesitation, but often got the light when we had
cool damp weather. From the time it had 50,000 miles through 100,000 miles
when I traded it, cool damp weather seemed to affect something. Had it into
the Chevy dealership twice and they were never able to get a code from the
computer (luckily they didn't charge me since the truck wouldn't spit out an
error code). Just learned to live with it.
