Cold start squeaking, drop revs then back up again, plz read - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

When I start my car (mainly just cold starts mornings) I start my car then my car revs up from start, then drops like 500 then I press's the gas to keep the revs up. I gass it and it squeaks for a bit then stops then the revs are normal again. Any suggestions why this happens and if someone else experience this?

Either loose belt or polished aluminum pulley.

It seems to new that I have like an extra load on my engine on cold starts. So you suggest me to get polished pulleys and loosen the belt a bit?

Check your belts as you turn on the whip splash a littld water on the belts if the sound goes away you got loose belts.

I'm saying your problem is either a loose belt or you have polished aluminum pulleys causing a squeak.

I had the same issue. I had a lose power steering belt, tightened it and problem was solved.

Let your car sit over night...
In the morning take off the fuel line from the fuel filter to the fuel rail...

If fuel does not gush out, you have a fuel pressure problem...

Either your injectors are leaking, your fuel pressure regulator is bad, or your fuel pump is dying...
