Exclamation oil pressure fluctuates when clutch pedal is down

well i looked into it and it seems like no one is having the same issue that i can tell.

i put a cam in and ever since i have been have weird issues with my oil pressure. when i push the clutch pedal in to come to a stop, the oil pressure as well as the idle drops then comes back up, sometime 3-4 times then equals out. also this will sometimes kill the car. also sometimes it runs like a champ.

i heard it could be in a tune (which i have not had done, im on tight budget right now)however i am worried that it might be internal issues.

also when i bought the car the previous owner unplugged the O2 harness, which drug on the ground and ate it up. i bought a new O2 and rewired it since it had no harness, i think i wired it up wrong cause i still get the trouble code. but to me it doesnt sound like that would cause such the issue.

just need some advice before i go spending money that i dont have.

Oil pressure is dependent on rpm. Get your idle stable and if you still have oil pressure issues then start to worry

other than your tune making oil pressure move your oil pressure sensor could be going out, just an idea cuz mine would fluctuate at idle in neutral but when i changed the sensor it fixed it

"i heard it could be in a tune"... You most likely heard correctly.

A tune will have NO effect on oil pressure, rpm effects oil pressure along with other things. If you have a fluctuating rpm you may have a slightly fluctuating oil pressure.
