I have a 92 chevy astro van, 4.3l 136000 miles. When I start after sitting for an hour, it smokes but stops rightaway may be in a minute. It is sluggish to take off and on a hill unless I accelerate hard. Service engine light came on and had it scanned for codes 13, 43, 45. I changed the oxygen sensor and did a tune up but no change at all. Please help.
