2000 BLAZER ZR2 4.3L AUTOMATIC 93,000 MILES

Okay so I was suppose to leave at 4 am this morning to drive 900 miles back home.

So i like you should before a long trip i changed my oil, i put in 5w30 royal purple and mobil one filter

I also thought that I should install a new cap and rotor, spark plug wires and coil since I've had the parts for two weeks now and thought maybe i would get better gas mileage if i did.

So i put them on and now when i start the car it idles really rough and backfires any time theres a load on it. Idling in neutral it hardly backfired.

I checked all my spark plug wires three times to make sure they weren't crossed.

Now I'm screwed cause i was suppose to drive 900 miles home and be on the raod right now.


i dont have a code scanner and autozone doesn't open until 8 am


anyone have any input????

 

plugs gapped correctly?? did the CEL light come on???

 

what plugs are you running? Hope they are platium.. cuz our rigs dont run the best with regular or for that matter anything other then AC's i ran Boch plat 2's and it didnt run the best and when i put AC's in it ran like a champ....

 

Is the cap sitting down on the distributor level? Are all of your wires pushed ALL the way onto the terminals on the distributor? I have witnessed plug wires backing off the posts on the distributor due to trapped air...

 

plugs seated correctly? cross threaded?
