Default Re: Can I live with these injectors till Fall?

Thanks Gerry

Given that my plenum and intakes are unmodified - I assume I would want the standard thickness plenum gaskets?

When the engine gets hot - say stuck in stop and go traffic for an hour - I can hear the flywheel chattering, although the engine isn't noticeably stumbling and doesn't stall ( I have also had an SES code for lean mixture). So I meaured the resistance of my primary injectors today, about an hour after a short 20 min run with the car. Resisatance values I get are:

Cyl 1 = 9.1
Cyl 2 = 12.9
Cyl 3 = 9.3
Cyl 4 = 12.9
Cyl 5 = 13
Cyl 6 = 5.8
Cyl 7 = 12.8
Cyl 8 = 12.6

I just ordered the Haibeck DVD, and would really like to avoid tackling a Plenum pull until the fall. Any reason I can't put this job off till then?

I was planning on going with the Accel product - price is atractive and I am not aware of any downside. ANy reason to consider another product?

Just saw this
#6 is probably not even working.

For the price i would change them.
It's cheaper them trying to replace a head gasket or worse.

Had a good discussion with Jon at FIC today - really helpful and knowledgable guy (and a ZR-1 owner). I ended up ordering the "Delco Look alike" injectors.

They are a Disc type injector made in the same factory (SMP) that makes the Accel injectors, Delco injectors and the RC injectors. They are flow tested and pre-configured to drop in (based on model year).

Great! I got a set from Jon and replaced all exactly a year ago. I went with Bosch injectors. Car never ran this well since I bought it in 2000.
