Another sr20 sputtering thread

[Redfox92]

I see countless sr20 sputtering threads, and none of the solutions seem to work for me...

About 2 months ago I was driving into the costco parking lot (no more then 20mph), grab a parking spot and go inside. When I come back out, and start up the 240, my engine (SR20DET black top) starts to sputter like one of the intake pipes has come loose again. So I check them all and they seem to be attached. With no other options, I drive home, the sputtering was consistent through all the rpm range and there was no bucking/ lurching/ bogging/ dieing.

Car sat for about 2 months while I bought a house and moved in.

Fast forward to today:

Car still sputters at any RPM any any temp (please note that it's very hot in Texas so the car is never actually getting "cold", just colder then normal running temp)
I removed all my FMIC piping, verified there are no holes in the piping or connectors, and reattached it all.
Tightened up my exhaust and verified there are no obvious leaks.
Put in new NGK BKR6E spark plugs gaped to 32
Verified every coil pack is producing spark
Verified my MAF is grounding properly with a multimeter
Installed a new 90 300zx TT fuel filer (auto zone brand not OEM)
Used the wooden stick in the ear touching injectors method to verify they are firing

I'm out of ideas, anyone else have one?

Figured it out....

I tested the injectors and got the following resistances:

cyl #1 11.5 Ohms
cyl #2 11.6 Ohms
cyl #3 11.6 Ohms
cyl #4 no reading at all

So I ordered up a new injector and it should (hopefully) be here by the weekend. woohoo!

Keep the thread updated and see if the injector fixes it.
