So here's what happend ,
washed my engine then went to start her up I got po102 code showing, I've had the same problem before and it was my throttle body,
so I changed throttle body still the same, changed IAT still the same, checked the ground sanded it cleaned, still po102 shows and car will not rev over 2500rpm, slip light,vdc ,check engine indicators all on, anyone have any clue what may be up with the G
thanks

 

P0102 is a MAF Sensor error. You can read more about it in the Service Manual if you have one for your car.

Sounds like you got water on your MAF sensor and your car went into limp mode. There are lots of ways to fix it, but the easiest way might be to just leave the battery terminal off overnight.

 

+1 - MAF Sensor. 3 Possible causes - Harness connector, Intake air leaks and MAF sensor. If it happened immediately after you washed your car, my bet is on water - either went into the intake and got the MAF wet (unlikley) or the connector got wet and shorted out. disconnect your MAF sensor and spray some WD 40 in the connectors, then wipe off what you can and reconnect. It's not a big deal if you don't get all the WD 40 off because it will not cause a short.

Other things to check - Air duct, vacuum hoses, retighten ground screws.
