Check engine light is steadily on. I recently changed my airfilter to a K&N for better airflow and possibily better throttle response. After changing the filter, the check engine light came on and is constantly on, the Car idles high and takes about 5 minutes to get to normal idle. In addition to that, once I step on the gas a little, the car starts pulling and remains around 1100rpm. If I accelerate, the car goes into limp mode, I get the DSC unavailable Error, The Cruise Control unavailable error and an engine fault. I'm guessing it has to be either a dirty or damaged Mass Airflow sensor issue.

I have not purchased a scanner yet, but intend to this Friday. Is there a suggestion you have that could help me get an answer quickly without spending a plethora of cash?? Additionally, I replaced the air filter with the original one but the problem still persists.

Codes are

P2135 Throttle position sensor A voltage correlation error
P0102 Mass or Volume Air Flow Circuit Low Input
P0122 Throttle Position Sensor/Switch A Circuit Low Input
P0101 Mass or Volume Air Flow Circuit Range/Performance Problem

Since my last post, I've taken the vehicle into my local Jaguar Dealership and they replaced the faulty Mass Airflow Sensor. Along with that, The performed the following as the part was under warranty.

** Warranty Throttle Body ***
Throttle Housing - Engine Set - Renew ??? (N/C)
Body - Throttle (N/C)
Gasket (N/C)
WJ4 (N/C)

What is a throttle Housing - Engine Set - Renew?? The other things I understand My total cost out of pocket was 296.00 and change.
