hey there. I seem to have a problem with misfiring while on WOT with my car. Even when it's fully warmed up, but really bad if it isn't. After replacing the plugs, swapping coilpacks checking compression and going to the dealer i cannot seem to figure it out. I just thought of something though. even after 2 hours of highway driving i noticed my coolant line on teh drivers side coming from teh radiator is ice cold. any idea's of why this would be and if it'd be causing my misfiring? it's been like this for a while, but my coolant temps always are in a good range so i never worried about it a whole lot. I forgot to mention this to the dealer, but it's been running alright this way expcept on WOT for thousands of miles.

 

I don't think that would be because of your misfire, if your lower rad hose is cold after a long highway drive I think that's a good thing.

 

but that shouldn't be ice cold. the radiator isn't that efficient. i was actually wondering if my waterpump wasn't working right or something.

 

If the engine is running 190-200ish, all is well with the cooling system. What did you gap the plugs to? .030-.032 works best for me.

Any mods on your 'Balt? I forget.

 

gapped to .32 i believe. i have hahn catless dp, catback, and intake. even with stock tune i have misfire issues, just not as bad. but they are much worse while tuned,..
