[bosshogg 0]

my raddo starts fine and drives ok for 1/4 mile then misfires jerks revs

die to erratic low 500rpm across all cylinders, no power to pull away.

Then if i remove the ecu plug spray WD40 on to the plug i get temporary

power back for a 1/2 mile then it starts again,sometimes i keep the revs

to 4000 and i can get it home.So far ihave replaced the following

4 x injectors

dizzy cap

rotor arm

plugs bosch

leads beru

fuel filter

 

to me its fuel starvation, but i dont get the ecu and wd40 bit ?

 

any idea dudes :roll:

Hi, I have a similar problem but you'll find it's probably just where the engine is flooding and the gap is giving it time to recover. I'm in the process of getting to the bottom of it myself but check out the cambelt.

Mine's doing the same. Quite scary on the motorway!!!

 

Taking it to PSI tomorrow, so if they uncover anything then I'll let you know.

Mine has been doing the exact same thing!! I found that my exhaust manifold was cracked (very common)plus my gaskets were leaking and this was giving the lamda sensor further down the system false readings hence over fuelling it. I recommend checking your manifold both visually and also listening for leaks.

Lamda wireing was cut at plug end to engine,tried to rewire but need another loom.

could the lamda be damaged due to wires cut ?

will i need to check the co2 again

hope to resolve this weekend :)

Lamda shouldnt be damaged from dodgy wiring, Sounds like thats possibly be the problem then! The lamda causes lots of probs when not functioning properly, let us know how you get on!

Andy at PSI couldn't find anything wrong with mine. I've had a new CAT fitted, but that's it for now. Seems to be running fine though now. Am going to give it an engine flush, injector clean and an oil change and see if that helps.

Mines been pin-pointed to the warm up regulator =)
