I just did a street ported 6 port...no emissions all blocked off..but when I started it it back fired real bad..then stopped after a while..it sat outside in the cold now it is backfireing again and wont idle or run for more than a few seconds............anyone have this problem or know what might be up?

I also have a buddy that is doing a 13bt swap and the TPS conection is different any ideas on that?

 

Are your plug wires on the correct spark plugs?

 

i think so
I put it on leading and trailing as marked...........is there anything else besides L1L2 T1T2?

 

I started it agian yesterday and it runs..idles real nice ..with a lope street port style..........I noticed that it idles better when I step on the brake pedal so i suspect a leacking booster or something.....
