Is it time for new injectors?
I thought I had a leaking injector so I pulled the rail and non of them are leaking. I think my pump is bleeding off but Im not going to worry about it.
Anyway, I had the rail over a couple of buckets and used the battery to fire off each inector with about 30 PSI of fuel pressure. Each one went off like a laser beam. No nice conical atomized flow. This was a dead straight fuel stream. Would I benefit from an injector upgrade? If so, which do you reccomend?
Car is not stock. It's bored .020. .202 intake valves and 194 exhaust. Headers, flowmaster, Cam is more than stock but not radical. Cold air intake. Plenum hogged out. Accel ignition, the usual stuff.
