Need help!!!! Please

[showtimesteele99SS]

My car runs rough from time to time in idle when in drive or park. No check engine light Ever! other then that the car runs great . When i start to accelerate its a little choppy especially after the car has been running for a good bit and when its either hot or humid. then after i get past 12 1300 rpms then it's back to normal. I think it might be an EGR problem but im not sure at all. Can someone help?

My Car
1999 Camaro SS LS-1 346ci ALL STOCK
67,000 Miles

I purchased it with 60,500 miles and have owned it for exactly 2 years.

Thanks in advance!!!

Start with the EGR and clean the maf, that maf seems to be a major source for a lot of little and sometime big issues cause it gets dirty.

Aslo to cover a the bases, check the tranny fluid level and the PCV line for breaks.

Has it ever had a tuneup? Might want to change the plugs, wires, and fuel filter also.

to be honest i have not had a tune up i have only driven it about 7,000 miles and i am the 2nd owner

Well it does have 70000 miles on it and the wires are now 10 years old. I would replace them regardless as preventative maintenence.
