Help needed Car starts perfect when cold no issues until it starts to warm up then itstarts to splutter then stops and shows check injectors
now i no there are loads of threads on this the AA said is was the throttle body but that works fine when its cold.
its had a new crank sensor fitter
it has had the garages diagnostics on and it came up with
Petrol (K4M - Diagnose - MT/AT) DTC Description
0638 - Motorised throttle housing control - Present
0638 - Motorised throttle housing control - Intermittent
0335 - Engine speed sensor circuit; no engine speed signal or speed signal interference - Intermittent
0105 - Intake manifold pressure sensor - Intermittent
0105 - Inlet manifold pressure sensor circuit; voltage outside tolerance limits - Intermittent
0105 - Inlet mainfold pressure sensor circuit, coherence - Intermittent
0420DF - Unknown fault code
0420 - Catalytic converter; EOBD threshold for HC pollutant emission exceeded - Intermittent
0651 - Sensor supply voltage 2; internal electronic fault - Present
the pressure sensor has also been changed this car is driving me nuts now and were at the end of our teather
my only thought is its over choking eg temp sensore but the garage says thats working
any ideas ???

Re: Will not run when warm says check injectors
It's not "injectors", but "injection", meaning the injection computer. How did it happen that there are so many codes? What's the full story?

Re: Will not run when warm says check injectors
Well it was working fine then the wife took it to work and as she pulled up it cut out, and would not start after some cranking the check injectors came on, so she called the AA he said it was the manifold (never checked it )
Items replaced
1. TDC sensor
2. Manifold
3 Air pressure sensor AA bust it trying to remove
the only thing I can think of is the Air Temp sensor
This is what happens
when call is cold it starts and runs fine until the temp gage starts to climb then it starts to splutter
then stops
leave for 20 mins and it will start again but only run for two mins then starts spluttering when is stops it smells rich eg smell of fuel
Oh the coil packs are also new
so I have been
Oh the codes were cleared and stayed clear until it starts to splutter sorry for spelling as not a good typist

Re: Will not run when warm says check injectors
After various head scratching and testing we oppted for the the accelerator pedal we changed this then cleared the codes
and started the car to warm this up straight away saw a change but we held our breath and Bingo
the car behaved as it should now were again
Turns out this is common strange that

Re: Will not run when warm says check injectors
Congratulations!
Shame you had to try all the other stuff before finding the solution to a "common" problem..
On a positive note: it's fixed!

Re: Will not run when warm says check injectors
Good thinking. One of the listed codes "short circuit to the ground" probably was causing secondary electrical problems. Well done!
