I know there confused lol...... but uhh thanks.

 

The owners manual clearly says do not race until the engine is warmed up. That was said for a reason.............although some cars are suppose to be driven right away after start up.......not the ss

 

It's a bad IAT2 sensor.

 

Logged it. iat2 works fine, no cel, logged it when cool outside and logge it when warm....sensor showed.fluctuation and within bounderies. Ill chrck resistance when.I.get the.chance...

 

Just replace it and see. The only two times I've seen issues with boost in neutral were a loose wastegate actuator rod and a bad IAT2 sensor. The sensor is pretty cheap, I think.

 

It doesn't do it while in neutral just when cold and he takes off.... he don't let her warm up.....

 

Oh, my bad. I thought this was in neutral. Sorry.

 

No bro and it its cool....

 

Let us know what you find out. These are good learning threads. Thanks.

 

Ah, IDK, I always let my car warm up to 180* Oil Temp and Coolant Temp before I drive it. Never had a problem. Car actually runs 1000x better in the cold.

 

Well mccullj ordered new plugs and a new evp. Valve, so when he gets this stuff then ill retune and see from there.

 

Plugs could have alot to do with it. No spark would mean no power. Mine does that sometimes on a NLS, if its not quite warm enough for that yet. It'll just misfire and the RPM's will stick. I changed my plugs, works fine now.

 

yeah he knows lol thats why i said i will not retune him till his car is fixed lol. he ordered all the parts so we shall see whatmy magic hands can do lol

 

just for the people that keep telling me not to beat on it when its cold...i stated that in the original post. i will not argue that i don't let the car warm up before driving it...but unless this issue is happening, it doesn't even go into positive boost while its cold. the only time it seems positive boost pressure when its cold is when this issue is happening.

 

refill ur rpm gauge fluid and it will be fine

 

thats funny to put in a thread where the people that are talking in that thread don't know anything about anything. but im pretty sure everyone in this thread has a pretty good idea of what they are talking about. so...thanks for your smart ass input...you can gtfo now. kthxbye

 

lmao good call mccullj lol funny, when you get your parts you gonna put them in....

 

Lmfao

 

yeah...my plugs should be here by the weekend. i got them from modern performance. my purge solenoid i ordered from gmpartsgiant.com. they say they take 3-5 days just to ship out...*******
