1999 pontiac sunfire injectors

[mesoman32]

does anyone know if the 1999 Pontiac sunfire can run both peak and hold and saturated fuel injectors.at this time I have 250cc RC peak and hold installed.i want to run more boost.so i have a new set of RC 440cc saturated injectors.thanks in advance.

wouldnt RC Engineering be the best source for an answer to your question. Seems like they have a good support program for their products.

 

[mesoman32]

yeah,i did ask them,but they were unsure about that specific car.

how about asking them for a 1999 Chevy Cavalier maybe they dont realize it's the same engine.

Well,I asked about the 99 cavalier.they said it was high impedance.i am sooo confused.the Haynes manual states that year is low impedance.I went to 2 local advance auto parts and used there multi meters.one showed 10.3 which is high impedance.the other read 2.1,which is low impedance.I do not know.

Are you measuring the resistance of all 4 original GM fuel injectors?

 

[mesoman32]

Yeah,I did twice.the first multimeter showed 10.3 .the second showed 2.2 .gonna get a third done soon. weird i know.

Quite often multimeters have to be calibrated to zero before using them when measuring resistance.

How do you calibrate one?
