the blazer starts and Idles fine. If I climb a hill, mid throttle bogs real bad until you floor it then it takes off. It is also down to about 11 mpg.
so far it has a new exhaust including 3-O2 sensors and 2 cadilidic converters , full tune-up, TPS, Idle button, and rebuilt fuel spider and regulator. It is showing no codes and this engine does not have an EGR. I'm into this thing for over a grand now and it still runs like crap. Any ideas? it only has 75,000 miles on it.
