question about my sr20 hesitating... could it be from lo oil pressure? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

my sr20 recently started having a problem with hesitating under boost... mainly 3rd gear pulls..but it has acted up in every gear

its almost like power is being shut off to the coils for a split second then it will climb a little higher in the rpms and studder again..

my car has low oil pressure as well. because i have a leak at the feed line.. i hate that dumbass banjo setup..

my question is, does the sr20 have a "limp Mode"? im wondering if my ecu is killing power to my coils because its reading a weakoil pressure

If you are getting hesitation, the timing is the first place I would look. Try moving your CAS around a little bit.

nah the timing is fine...

also i have a mixture of weights in the oil because i ran out and had to put 5w30 in it

Check your ECU for codes and then clear them,

I noticed mine had a code for CAS and Knock Sen, once when I had a Slute pop off, misfired in first gerar and sometimes around 10-25% throttle cleared he codes and it went away after 20 mins of driving

I was just trying to help identify a problem. Now that I think about it, a timing issue would act up all the time. So you think he has a major boost leak, sometimes? Mainly in third gear? haha

the line coming off my PCV valve that goes to the back of the block poped off at the block ... i think thats what was doing it
