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.

 

Bump, anyone? I'm at my wits end.

 

What do you mean threw the timing off? Ignition timing is determined by the PCM. Are you now setting a code and the SES light is on but the miss is gone? What do you need help with? You need to explain in much more detail.
