I assume your CEL is on also? If you don't have a code reader, it's just a pure guessing game. It's going into limp mode, the reason why? Ignition system, wiring, fuel system, computer failure, throttle body, maf sensor, etc etc

ok Mark, tks, I understood, I need to check the codes , it's possible to check without a code reader , or use a common one ? Where is located the connector to read ?

Any obd2 code reader should get you some codes. It's under the dash. No other way to get codes...it's not an old one with flashing lights to signify codes... Besides with the amount of codes we have these days, you'd be counting for 30 seconds :)

Hi Mark, take a look ... E P 1339 E P 1233 E P 1338 E P0057 H 02 S HEATER CONTROL CIRCUIT LOW P P0057 H 02 S HEATER CONTROL CIRCUIT LOW

what means the letter E in red before of code ( E P0057) and the letter P in grey before code ( P P0057 ) ? Because the last code was repeat,only changed the letter and color .
