Stalling problem
On my car I'm having a problem where i go to start my car in the morning when it's cold and it is hard to start. It eventually does start but idles rough and then drops rpm lower than 800 and stall out. This morning I started it up and it stalled right away. It begins to run better once it's warmed up.
I've been having this issue for awhile when I put it on the road in march it was fine but in the middle of April it started stalling. I thought advancing the timing from 0-6 (factory spec) would help but it got worse. I put in new injectors because I had the problem before winter and it seemed to run better at the time. Not sure what the problem is now. Could it be sensors? Please I could use the help. The stalling is embarressing hahah

It's a 90 corvette, yes it's an L98
Spark plugs are good and fairly new I checked them
Oil pressure when I start it is up around 80 then when it warms up its about 40
Not sure about fuel I gotta check it
Plugs wires are brand new
I could have an issue with the cap and rotor maybe I need a new coil?
I could also have a vacuum leak but I don't hear one

Only code is for the speedometer, I've had it for while. It hasn't worked since I bought it

pretty common for fuel delivery to become intermittent, as there's a pre filter or sock on the fuel pump pick up, and there's a fuel pressure regulator under the plenum
there is also a fuel filter on the passenger side
do to the cars age these components require inspection and good maint on a car you're going to keep may warrant replacement for satisfaction of just knowing you've invested money in to dependability
the Delphi pump and carter sock or pre-filter can be had from rock auto most will say buy the complete pump/sending unit
having a fuel injection pump testing pressure gauge set up is a must for anyone doing diagnostics harbor freight has a cheap set
look for signs of vacuum leaks first $$
you sure as hell aren't going to hear them it's a visual inpection of all hoses related to anything to do with vacuum
look around the intake better yet pay someone

A vacuum line broke on me trying to put the motor back together but I fixed it with a rubber hose. I was thinking about changing the coil in the distributor first because it hasn't Been changed but I will look into the fuel filter. It has to be either fuel delivery, ignition or air. I'll let u know what happens when I get the new coil I believe i got a new fuel filter when I bought it tho. But the one I'm the pump and intake could be old
