Kangoo 1.2 2002

[robreigns89]

I have a kangoo 1.2 2002
It has P0200 and P0134
has had 4x new bosch spark plugs in.
new coil pack and leads coming tomorrow.

was stood for 6 weeks then drove it 40 miles on motorway trip and it was fine.
later that day i topped fuel up and about an hour later it began to missfire.

hit and miss now. missfire not present on first start when cold, once warms up about 2 mins in missfire returns.

Just been out in it and no missfire. but im sure its not gonna stay away.

Could this be down to a failing coil pack or HT lead.

P0134 is precat lambda sensor, so this will affect fuelling.

P0200 is injector circuit malfunction... is the black box will covering the ECU connector and the back of the rocker cover? If so this can/will chaff the wiring at the plug and cause all sorts of faults.

P0314 - Single Cylinder Misfire (Cylinder not Specified). (not 134) mistyped.

P0200 injector citcuit malfuntion / open.

1 min drives fine next misfires
sometimes takes off fine and 2 mins into driving it starts misfiring

im changing the coil pack and ht leads tomorrow because one ht lead looks shot and when i take ht lead off 4 it dosent change anything where as 1 2 3 would cause it to get worse or stall

Swap injector 3 and 4 round and see if the fault follows it.

 

[robreigns89]

i swapped 3 and 4 earlier and caused the car to stall. when removing 4 nothing changes.
However randomly since about 3pm the car hasnt missed a beat... is there a very small chance a dirty injector has cleaned itself
