Ok so lately Ive been having this problem after driving the max VG30E on the freeway after 40-60 miles, at one point the engine starts to buck,miss and smoke it get worse after I get off the freeway. I can smell fuel in the exhaust and I have to keep the RPM's up to maintain freeway speeds. So it happened again today,earlier this week I did an OHM test on the injectors and they were within factory specs 10-14ohms. So as soon as I pulled up it was running very rough and smoking, I pulled the plugs 1 and 3 are similar looking in the pic on the left, #5 was fuel soaked, I could smell the fuel from the plug hole. plugs 2,4,6 were fine. I changed the wires 2 days ago and the firing order is correct. So I'm thinking fuel injectors or FPR...suggestions? (sorry for the bad pics)

well after changing the plugs and taking it out for a drive, it started to run real bad, the smell was something Ive never smelt before, it was smoking under the hood and I looked under the car and the cat was glowing orange....so I guess from the bad injectors dumping too much fuel into the exhaust it burned out the cat causing the lack of power since it's probably clogged...sigh,like I need this problem since smog is next week...

 

#5 plug looks rough. I just had a similar problem with a wild bucking gxe. I was so worried about the fuel injectors I kept pulling plug wires while the car was running to detect a change in idle. In the process I pulled the plug wire from #3 plug and the metal piece inside the boot cwas left stuck on the plug. I put the wire back down on it but I guess not good enough. Car backfired and ran like crap. I finally troubleshot around and pushed the connector up in the boot with needlenose for a better connection...must have been it cause she fires like a diciplined soldier...Ifigure with the pics a real whiz unlike myself could help this fellow out...The devilz in the details
