Couple of problems with my 4.3
How's it going everyone. I'm new here, just recently picked up a 98 Blazer LS with 160K on it. At the moment I'm stuck. She seems to be acting up rather oddly. At an idle, she'll misfire continuously on cylinders number 4 and 6. With a scanner hooked up you can watch the misfire count continuously climb. However, once you give it a little gas, she smooths out. But once the RPM's drop back down, she wants to stall out. As of this moment I've changed the distributor, spider, spark plugs on cylinders 4 and 6, cleaned the MAF and checked to see if the wires were crossed somehow. I need some help with this thing. I'm at my wits end. Also, the steering is very slouched. I can turn the wheel a quarter of a turn and the truck will continue to go straight. The misfire is on the top of the list of what needs to be figured out. When I installed the new distributor, I installed it one tooth off on the gear which solved the misfire, however threw the timing off. I'm just so confused at this moment. Any help would be great.

With a used truck with 160,000 miles on it you should be doing a complete tune up on it instead of of changing a part here or there. The spark plug wires might be bad. Did you do a compression check on 4 and 6? Since you don't really know the history of this truck, you need to check everything.
