Daewoo Kalos 1.4 8v 2003 - Code P0300 random multiple engine misfire #

Posted by Andy Mason on September 25, 2012, 3:56 pm

Year of Manufacture *: 2003
Engine Size and Code *: 1400
( Optional ) Scanner Used: verdict, omiscan and more
( Optional) Fault Codes: P0300

we have supplied and fitted a low mileage second hand 8 valve engine to this car, after the camshaft seized into the head of the original engine.
Runs superbly but P0300,random multiple engine misfire, comes on after a similar distance of about 1/4 mile.Clears but comes on again after same distance.
Engine came bare so swapped over camshaft and crank sensors etc. no fault code on original engine.
Have checked compressions, run and flushed engine.
Customer has had car back and run for 1 week and car hasnt missed a beat, but code still clears and comes on after about 1/4 mile.
We have checked speed sensor connections etc.
Any ideas appreciated
Andy

What is live data telling you?

MAP readings?

AMM readings?

Fuel trims?

Injector times?

Hi Andy,

In addition, I would be interested in the 4 gas readings at idle and fast idle. I assume nothing of interest is shown in the freeze frame data.

I've had p0300 caused by head gasket on this engine. Not the height of engineering excellence.

All live data reading correctly, oxygen sensor switching slightly faster than it should, but light has now cleared and has'nt come back on.
Customer has had car back and following a follow up call, she has said light still off.
Car has since been back in, running fine and light still off
