This is my first post. I have been reading a lot off these forums to fix other issues with my Blazer. Hello everyone!

First things first. I bought the blazer, drove it for about 3 months, I didn't have a miss or any issues at all. However, the heat in the vehicle wasn't very warm and I noticed the temperature gauge was reading just a hair above the lowest reading. So I went ahead and grabbed a new thermostat, which fixed my temperature/heat problem. It also made the check engine light go off. So I was pretty happy about that.

A day after fixing the temp gauge I starting having odd misses under load. Only if I push the gas pretty good or if I'm going up a decent sized hill. Doesn't matter what RPMS. If I'm easy on the gas it's missing and it'll still miss if I push the gas going up a hill. After it missed the first time the check engine light came back on. It has been on since.

So I started reading online. I ordered a distributor repair kit, coming in the next couple days. I also ordered the coil, which I replaced today. It didn't make a difference at all what so ever.

I have also, had a weird issue since replacing the temperature gauge, where the gas pedal does nothing at all. It has happened 3 times now in the last couple months. It just seems like it has lost all fuel and isn't firing anymore. The engine drops all the way out, but only actually turned off 1 of the 3 times it happened. It doesn't struggle or anything, it technically just drops to idle and acts like the gas pedal is accelerating it. It might last 5 seconds and then it'll continue running as if nothing has happened.

Sorry for typing a book. Any help would be appreciated. (I haven't gotten to autozone yet for them to read my error code)

 

Not sure if you have any history/maintenance on the vehicle.

I'll start this off with checking your catalytic converter. It could be plugged.
You'll know more once you get the code read. I am sure more people will
pitch in to help you out. Get the Code Info.

I don't know the history on the vehicle at all. Sorry, also I'll get the codes read tomorrow.

 

So I went to autozone real quick before they closed. I had 4 codes. 2 of them was separate oxygen sensors, 1 was the random miss-fire, and 1 was the miss on piston 1. (Mind you none of these came up until it had the very first miss)
