so i took the spark plugs out and they had gas on them, the plugs are Bosch Platinum series

Smith-02

shouldve got the +4 plugs. anything less and you'll be lucky if your car runs on 108 octane and a 100,000v coil.

When i crank the motor over the exaust is makin a poof sound, and i deas

veracity

are you sure your poof sound is on the exhaust side and not more of a backfire? might pull your valve cover off and make sure you still have all your valves. happened to us in my bud's hatch. otherwise, it could be a handful of things. timing, plugs, sensors. you should definately listen to the guys above and eliminate that chip possibility first. your map may be floodin the ---- out of your cylinders. explain your rough idling and soaked as ---- plugs first if you KNOW you got spark. good luck and don't forget the infamous loose (or off) ground wires if you've messed with any of them

Did you ever think that the map itself is probably all messed up? Obviously the first sign should've been the rough idle when you first started it. Did your friend scale for 450's and then correct for injector latency? Too many things that it could be, but my money's going toward the bin file.

So i got the car started today, i primed the the motor a couple of time and then unplugged the injectors and tried to start the car and i t ran for like 2 secs. and then i plugged the injectors back in and started the car and it ran fine, but when i reved the motor it sounded like it was missin, any idea, they are 450cc injectors, i dunno if its dumpin too much or not enough fuel
