hi guys, my rs2000 has a slight missfire but this doesnt effect the performance atall

ive checked the leads, plugs, compression, power to coil packs

my next thought is injectors, any ideas

 

Id say a coil pack .. Sometimes they break down under load.. you cant test them..

Guy on ebay sells them cheap..

 

why cant you test them, you can measure the resistance to test for an open circuit

 

wheres te turbo?

 

i had this problem with mine it turned out to be the 2 ht leads. I replaced them for some thick core ones n neva had a problem since.

*goes and touches wood*

 

get the injectors checked or

 

You can test the coil packs just like you check a normal coil.

 

the cam in the head you sold me was fuked mate, the rs2000 is just my runaround

 

will try a new set of leads cheers guys

 

if the piston rings were gone i would loose performance. and theres no lose of compression,

 

that happened with no miss fire just more or less stalled a bit lumpy then nothing no warning running sweet as

 

fuk ever find out the cause? thats got serously hot

 

the engine was completely fucked was doing about 50 mph when it just slowed down no miss just no power then went lumpy and stalled, when the head was off that had a crack and the bore was smeared with melted piston but there was no advanced warning at all nothing. mind you it had done 130,000 so i broke it up. when checked we were told that a partly block injector let it get so hot and that was it no bang nothing couldnt believe it never mind

 

air injector?

 

no number 4 fuel injector

 

 

i had the same problem a few months ago. it turned out to be the wires that go to the coil packs. the had small breaks in the wires. the proplem being that the wires are part of the engine loom and can be difficult to find a replacement unless you get one custom made for around Ł300. i took mine apart and managed to repair the dodgey bits which was a task on its own

 

problem solved - after starting fresh, doing all the basic checks i done another compression test - showed 40psi no. 1, done wet test which didnt change a thing - wipped off head, found a burnt out valve caused by overfueling. fit new valves - sorted
