And I wonder, I still wonder, who'll stop the rain.
Just got given a 91 integra from a friend, its been sitting for almost 2 years due to the fact that it runs like poo poo and will stall constantly.
What i have done so far is:
replaced coolant temp sensor
replaced idle air control valve
checked compression 180 on all cylinders
checked spark plugs
checked dist cap and rotor
checked for vac leaks
checked air filter
checked tps sensor
no stored codes

It feels like its running on 3 cylinders and if you give it some gas sometimes it will pickup and seem to run fine.

Any input would be gladly appreciated.

What's your fuel pressure like? It might be prudent to go take a gander at the fuel filter.

i was going to do that but i dont see a valve to hook into, i may need to invest in a fuel pressure guage.

I would probably just go ahead and swap the fuel filter anyway, if it's easy to get to (is it internal to the tank on Integras? Shouldn't be.)

e: Nope. It's easy peasy. http://www.clubintegra.com/board/showthread.php?p=916783

If swapping the fuel filter makes it a little better, chances are the fuel pump is not doing too well either.

thats not a bad idea, i will grab a filter tomorrow, but the filter thats in there looks very new but its worth doing to be safe.

Ignitor (inside the distributor) does weird things when it goes bad. Is the tach twitchy at all?

What have you assholes done now?
Also important to note that just because something has been replaced, does not rule it out from being faulty. I've had plenty of new parts poo poo out in a matter of days, or come DOA.

Also check all the grounds. Older Hondas are always picky about grounds.

I know these little bastards can cause issues but i always thought they just died and caused a no start, but im going to the auto wrecker today so ill pick one up just to be safe and im going to grab a maf sensor to be safe as well, is there any other small sensor-like items i should grab to test while im there?

did a good look around at all the grounds and they seem good under the hood, have yet to check if there are any under the dash.

FIXED!

it was the motherfucking spark plugs.

after talking to my buddy at the auto wrecker while picking up a map sensor he told me he had the same car long ago with the same issue and it was spark plugs.

even though they looked fine it was the thing i should have changed first.

thanks for everyone's input.

truthfully as long as there on metal and not a painted surface they should be ok.
