Help!!! Explosion and smoke coming from intake grill!

[Dgnarvs]

Okay, the shop has put everything back together but it now appears that the car is in limp home mode and RPM whilst on stop cannot get past 2000.

A bit of background... The battery died a few days back because I haven't used the car in weeks. Bro got it jump started and brought to the shop to replace the battery.

I've done some research on the forum and it appears a few others have had similar experiences about the limp home mode after battery dies. I hope it's just a case of resetting he codes... I've read others had to replace the throttle body!

Still don't know for sure what caused the explosion/smoke.

However, all of these appear to be connected to the intake. MAF issue? Throttle body? Crap!
