it might be engine coolant sensor on it maybe and about the headers yes those headers from edelbrock do give you some more horse power. i own a 96 s10 and 89 jimmy the jimmy is the evey day driver and both are 4.3's and in my opinion from driving both of them the jimmy has more power to me because it came stock with a posi that might be the reason. but hope i helped a little.
