New To Skylines

[dionmr33]

Hi I'm new to owning a Nissan skyline. I recently bought a R33 GTSt skyline from a friend for cheap. The reason being that after about 20 mins of running the engine starts miss-firing and loses some power. still drivable but annoying none the less. My friend had told me he's taken it to his family mechanic and he couldn't work it out. Would anyone on here know of or had a similar problem with their skyline? If so could you please direct me in the right direction? Thanks

could be one of the following things:

1: needs new coils

2: needs a new ignitor pack (if it's a series 1 r33)

3: has a faulty temp sensor

4: has an overheating issue

5: has a dodgy fuel pump

6: has a faulty CAS (crank angle sensor)

as well as a few others

numbers 1, 2 or 6 (not as likely as 1 or 2) are the most likely causes since it seems to be heat related.

Does it feel like it's mis firing?

My engine does something like this. The only way I can describe it is the feeling of a spark plug failing, but I have brand new spark plugs and apparently there's nothing wrong with my coil packs

If you figure this out, you're one up on my mechanic.

jacob, what is your coil pack loom like? the wiring in it may be dodgy.
