Missfire after running TD04 at 1bar

[gizzy98]

I got the car checked at Powerstation on the dyno to check the fueling was spot on to run 1bar on my TD04 and Jam ECU and Tial ext WG.

The fueling was spot on and the car was running fine on the dyno and the rest of that day.

The following day the car wouldnt boost to 1bar and was almost missing/hitting a limiter.

Now the car is misfiring at low revs off boost.

Any ideas on simple/obvious things to check first?

Check your ignition system is ok ie distributor and rotor arm, spark plugs and leads... IMO i would say its going to be your distributor and rotor arm.

Thanks buddy,

Would running the higher boost be enough to knacker them out then do u think?

It's just wear and tear really best check them all but I would start with the dizzy and rotor arm

Cool, ill change the leads, cap & rotor arm.

Made me think actually that the day of the dyno it was absolutely pissing it down. Just pulled out the plugs & the two under the vent had a load of water round them so I've cleaned them up & will try that as that certainly wouldn't have helped matters, cross fingers.

Thanks buddy
