Hello All! I have resurrected a nice 94 eclipse 1.8 non turbo for my daughter's first car. The car sat for 10 years in my garage, ready for paint. It's super clean and now has a sweet paint job (factory paint rep here).
I've changed the tank, pump, lines, timing belt, belts, hoses, filters, O2 sensor, Air Flow meter, PCV valve, installed a bi-pass test pipe in place of converter. I'm running NGK Plugs and the burn appears fine. The car smells like it's rich (very light trace of tailpipe smoke), but it's shutting down power, or stumbling on acceleration. When this happens, sometimes you can clear it up by flooring the accelerator for a bit, but sometimes, it simply bucks, looses power, stutters and shuts down. If I stop and turn off the key, then I can start it right back up and am able to take off fine. I'm bewildered, and really need your advise and expertise. It's my daughter, guys... so I don't really want to, and know it's somewhat pointless to, do anything but drive this little 1.8 as it was designed. 27 MPG isn't bad, ya know!

ANY Help and advise is greatly appreciated.

(when I changed the air flow meter, the car ran fine for about a month, then it's back to being a problem again. )

 

how's the throttle cable tension by adjusting with the screw on throttle body and is the distributor advanced or retarded little stuff like that could cause your issue
