Hi,

I have a ca18et in my 910 bluebird wich isn't running ok.
When I start the car and everything is cold, the engine runs fine, but as soon as the engine warms up, it starts to shake and won't rev smooth.
The timing is ok.

I use a twin spark engine, with the electrics of a single spark engine. I use the sparks at the exhaust side as dummies and the intake side as the working sparks.

I find it strange that is runs fine when cold, but when it's on temperature, it's not running smooth.

A short clip for more details below.

Thanks,

Check maf, o2 sensor and timing. if that don't work, wiggle some of your connectors..

also check your water temp sensor as that could also be a factor

Lol the only reason I know of this is because when doing my bartco swap I ran into the issue of not being able to hook it up as the wires weren't long enough i didn't think it was a big deal till I drove the car and it wouldn't start after I shut it off till it got warm lol or it would just shut off because it didn't know how much fuel to inject lol

a bit late, but it was the o2 sensor. :)

Good to hear that you got it fixed.  And its never too late.  It is annoying when someone doesn't post what fixed there problem so that other members new and old salty dogs that forget things can look up what you did.
