ProbeGT-ZE

alright, here's the deal...my 1g talon runs GREAT, but tends to stumble under heavy load...i've been driving it really lightly...anyway...whenever i decide to hit it, she tends to stumble around 5000rpm...i went ahead and replaced the badly worn spark plugs, and that seemed to help when i give it about 70% throttle in 2nd all the way to red, if i floor it, it tends to stumble...i know, i should get new plugs too...but other than that...what could it be??

BTW, i need help tuning my S-AFC...w/o an EGT or a wideband o2, it's kinda hard...maybe i should look into getting a boost gauge too haha˛...anyway gimmie a hand guys!

I had same problem when I punched it before I tuned my SAFC. I was runnin rich and needed to lean out, you could have the same prob. What's you're mods and current AFC settings?

plug wires. check your mas air flow sensor, and check timing!!!, fuel pressure regulator working properly? possibly o2 sensor dirty too
