Sputter Problem!!!
 

I have a 04 SRT-4 Neon. It has a long list of mods like GT35R, Mopar cold air intake aftermarket fuel rail with 1000cc injectors, large front mount and so on. Well my problem is that all of a sudden lately it has developed a sputter at cruising speed. Well I watch my wideband and nothing changes when this happens but when I watch my S-AFC on the graph it shows my throttle line jumping up and down. Does anyone have a thought as to what it could be?

Have you pulled your plugs to see if they're fouled or anything? Or have you recently fueled up and maybe got some bad gas? Does it do this all the time or just at part boost? Does it go away at full throttle? You need to give more info to get help my friend...

Start with the easy and replace the plugs. You probably need to lower the gap.
However, I have had this problem before and had to replace the wires.

I agree with the first thought being sparks and wires. Like shadow asked, when does it sputter? Only when cruising, accelerating?

Well he has replaced plugs and gapped them and also the plug wires and the coil. We think he got a hold of some bad gas and since then it has been doing fine.

I hate when I get bad gas.

Good ol Ram
