i just got a cel code come on. the car was running fine all day. i just started it up and the idle is a little rough now but not totally bad. it does make a weird click after i let off the gas when i do a quick short blip.

so i just ran the vcds in the car and got these codes.
p0303, p0304, p0300, p0302

what do you guys think it could be?
the dealership recently fixed my coolant leaking issue. forgot what they replaced but i think some part was leaking so they replaced it.

car does not have a tune. its got the stock ecu.
the engine mods are the GFB divertor valve, lighter crank pulley neuspeed, hi flo discharge pipe conversion neuspeed. all these have been on the car for over 2 years. never an issue. would any of these cause the issue now?

the other question is, is it safe to drive to my dealership tomorrow with this issue. its about 15 miles away? should i just tow it?
