this is my mani and turbo after a trip to walmart(which is 5 miles away) i stop to get food and sat there and idled. now i was idling for like 10 mins. i have seen my mani glow but never like that.

i started having problems with the probe last saturday. i went out friday night trying to get my fiends Gtech thing to work for my car and in the middle of shifting from 3rd to 4th the car sputted on me some what and then picked up. nothin else happen that night but then i saw that i had some radiator problems and had to switch a new one in there.

the car sat for 2 days till i got it back on the road. and when i started driving it again it was sputting some again nothin bigg i thought it was just the cold(i live in pa and it like 30 out). so i got on it and it boosted to 15psi no problem but it felt like it didnt have that prower that it had before. any clue one if i blow something with the turbo again?

i would think tht it might have something to do with my coolant. becuz i had to change my radiator cuz it cracked. so i think that there is something blocking some were. so i will chaeck my line tomrrow. and if its not that i will look into my fuel. i havent added anything to the fuel. so i will check the injectors.... i need this one to last some what longer...

Colder air = denser air

Denser air = higher combustion pressure

Higher combustion pressure (without adjusting fueling or timing) = hotter combustion temperature

Hotter combustion temperature = higher EGT

But as stated the ECU should comprenste for any increase in air density.

I think that with more driving in the cold temps that the ECU should correct the situation.

Remember that during the first few minutes or so of running that the ECU does not trim fuel according to the O2 sensor.
Because the sensor is not up to temp yet.

your timing isn't stock? What did you do to it?

When you drove to walmart, were you WFO ??

Looks normal to me.
I've driven my HARD before, and it's never gotten that red hot where the whole manifold is glowing :lol:
