I had my transmission rebuilt and when I got my blazer back it was running rough. My husband did a tune up on it and it still ran a little rough but was a lot better. Drove it about 6 months and then one day it stalled. Started right back up. The next week it stalled again and started right back up. The third week it stalled and was missing really really bad. He changed the egr, iac, tps.....and plugs....ran good for a few days. Then it started missing again and stalled. So he tested the fuel pressure and that was good. He pulled the plugs and number 5 was wet and number 3 had very little wetness. So he changed the spider, regulator and plugs. Ran pretty good for a day then it started missing bad again. Before it started missing I was driving it and it felt like my car had stalled, my rpms went down and so did my speed but in fact it had not stalled it only did this once. The # 5 Plug was wet again and the intake was wet inside and when I checked my oil the level was higher so we assumed gas got inside so he changed the oil and fuel lines that go into the intake. He checked to see if the injectors were leaking with a paper towel and there was nothing. He did this by turning the key on to prime the pump.

 

Are there any check engine lights? If so, what are the codes?

 

So now if your still getting a no fire on five, secondary ignition, cap, wires , rotor.
