Over the last week or so, intermittently, my car has felt sluggish and not responsive at times.
Usually I've noticed it from cold as the get up and go is not there and throttle response is lack lustre to say the least. Other times it's been spot on.
3 or 4 times now when I've pushed a little as soon as the car hits around 4k revs in 3rd gear it's like I've hit the rev limiter hard and the car loses ALL power and slows to around 30-40 mph and the engine feeling as though it's going to jump out of the bay as it's almost as though all timing has gone, it's lumpy as hell.
Yesterday it happened a couple of times, plus at one point I had to drop from 6th to 3rd on what was really only a gentle upwards incline, a hill I'd normally take in 6th and accelerate up.
Also from a set of traffic lights yesterday the car was fully out of puff in 1st gear at 2k revs.. it's like it's severely restricting performance.
Anyway I've pulled the codes with my Peake Code Reader even though the EML has not come on.
74 - Servotronic valve current
AA - Secondary air system, flow too low... not worried about that as happens on virtually every car
29 - Air mass sensor, Cyl #1-4
81 - Catalyst protection engaged, fuel tank low - Odd one as I've not let the car dip below 80 miles range on the OBC for several years
90 - Fuel control, Cyl #1-4
91 - Fuel control, Cyl #5-8
Would I be right in assuming the MAFs are the culprit?
Guidance sought from the knowledgeable please.
