Ok so I bought my truck last year in december, so ive had it about a year. When I got it it was completely stock, so no problems with it at all. So since then, ive done these things to the motor, SC 3865, K&N CIA, Shorty wires, Efan. I say what ive done to it to see if anyone else has had any probs with this same thing because of one of these. The last couple of days, after my truck sits all night in the 10-20 degree temps, I go to start it, and it just cranks for 5 min, and coughs and chokes, and sputters but wont fully start, now after about 10 min of trying it will start and blow some nasty stuff out the exhaust like its really rich, then it will say check gauges and my oil pressure gauge shows no pressure, so I turn it back off, and restart it, it fires right up and oil pressure comes back to normal right off the rip. WTF????? any suggestions??? I have noticed that it seems to have more trouble starting since ive installed the shorty wires???? dont know why but it runs great after you get it to run, shut it off, and restart it... But i surely dont want to have to do that every morning, I think my neighbors are getting pissed, not to mention im getting pissed, and it sounds like I drive a POS!
