My S12 full white RS-X

[MrDan]

Don't really know much about where to put pics up so i thought here would be ok!
Plus i have a few little problems so i thought someone would be able to help.
Here she is.




Problem is the car has some flat spots, i put some new plugs in and it helped, but it's only an intermitent problem, sometimes it goes very well and other times it's really flat, sort of on/off/on/off power!
Someone help! cheers Oh and it has a CA18 DET engine in.

check the fault codes on the ECU to help but maybe the ignition coils (one for each plug) are intermittent

Does it do when it's hot and when it does it is it running on three cylinders?
If so it could be a coil pack on the way out as they tend to sot working when hot before failing all together.
