hi, my name is Tim
does the car have any power problems when the light is on?
Yes, it has less power. He was told by the Ford dealership that the light is a safety feature to protect the transmission and when the light is on, it cannot go up to full speed.
It is not to protect the transmission, its to protect the engine, you will need to scan the computer for codes, if the light was on, then it stores a code, we need the code to diagnose this, but some of the most common problems are a dirty throttle bore or a bad throttle body, but the codes will be neccessary to properly diagnose this, Autozone and most other parts houses will pull the codes for free, can you have this done?
Yes, he can take it to Autozone. However, he says the last time he took it to the dealership they ran it on the analyzer and said no codes were stored and the light has not come on again since then. That was probably 4-6 weeks ago.
these have a problem also with the airbox not sealing, either from a bad seated airfilter, or the lid on it not sealing, has he had the airfilter checked or changed recently?
He has changed the filter several times, but he'll check to make sure it's all tight. Regarding the codes again, will Autozone be able to detect a code that the dealership could not? I don't want to send him to do that if it won't be productive. Thanks.
I have to leave for several hours, but I'll be back later. Thanks!
Are you there Tim?
