I just did a swap and the car turned on 5 months later.
It would start up perfect and isles perfect then it would just drop to like 200rpm and eventually shut off.
Could it be the old gas? Or anything else? It had maybe not even a gallon of gas so I added a gallon of fresh gas. It got little better but still not drivable

Thanks in advance

 

I would drain the gas, put in fresh gas, flush the lines, [remove gas line from filter] allow fuel to flush out of line, replace filter and try again. 94

 

I just put in new gas after I drained new spark plugs. Still the same. Sometimes I have to push the gas hard for it to even rev

 

cap rotor wires? do all youre basic checks first any codes?

 

Mine does the same thing but if I hold the gas for awhile it gets better till its warm then it kinda idles high... People keep saying idle air or fast idle... havent had time to check them... Maybe check those?

 

another thing is that my vacuumk reads really low
last swap was at 20 psi now its reading barely 10

 

no no check engine light wires and dizzy works fine

 

when i first start the car its perfect but maybe lets say like 1 minute later rpm drops to like 200 rpm. i just tried driving the car and basically if i let the gas go it would almost die. and when i try to press the gas its not really doing anything so i have to press the gas pedal past halfway for it to rev back up

 

hmm could be fuel is flooding, I know i had an issue with #1 cylinder and it did that on occasion. It was comp. rings... went bad. Is your lil screw that sets idle screwed all the way in? could be your problem as well...

 

its not all the way in. its at the point where it idles fine.
and i dont believe its the rings because this block is freshly rebuilt with all new parts

 

You said your vacuum only shows 10inhg or its set to 10psi? Hows your dis. new used? Fuel relay? Man i just had a similar problem, sorry I can't help more.

 

Dump fuel, flush fuel lines, replace fuel filter.

Even if the above is not your problem, it can't hurt and if for no other reason then to elliminate them as the possible problem. 94

 

I'm pretty sure it's running rich as **** so I'm bout to get on the dyno tomorrow and see and will let you guys know. Thanks for all the help
