New to forums, never used them before as I usually take the car to the garage to get fixed, but I want to try and solve this myself

I get the error code P1103 when driving, and the amber engine management light on, and occasionally the P0299 code

Whilst driving, if I go slow in 3rd or 4th gear, the car judders, 

If im in 4th or 5th, and the revs go over around 2200, I get the red triangle 'engine malfunction'

I can clear this code, and the car is ok again (but will still judder)

It also seems to use a lot more fuel than normal

 

So far, i've changed the MAF sensor, air filter, fuel filter

 

Can anyone point me in the right direction to help me solve this, before I end up taking it to the garage!

thanks 

Was the MAF you changed it to an OEM one or aftermarket?

What are the common causes of code P1103?

The common causes of code P1103 are largely the same across all Ford applications, and could include one or more of the following

• Damaged, defective, unsuitable, or malfunctioning MAF sensor
• Use of unsuitable aftermarket MAF sensors on some applications
• Damaged, defective, unsuitable, or malfunctioning IAT (Intake Air Temperature) sensor
• Damaged, shorted, burnt, disconnected, or corroded wiring and/or connectors
• Air intake restrictions
• Leaks in the intake air system or ducting
• Note that on some Ford applications, some types of EGR (Exhaust Gas Recirculation) system faults and defects can cause this code to set, or contribute to its setting. Therefore, if the affected application is fitted with an EGR system, be sure to scan specifically for active and pending EGR system trouble codes as well
• Failed or failing PCM, but note that since this a rare event, the fault must be sought elsewhere before any control module is reprogrammed or replaced
