 O2 Sensor or more??
Hi,
Bought an 89 hatch, 2.3EFI N/A LX, automatic. Found a LOT of things wrong with it, corrected them and it has helped, but still is not right.
Here's where I am now, car starts great and idles fine until it gets warm and rev it up, when it comes back down it will lope from 600-1100rpm looking for idle. Sometimes it finds it, sometimes it stalls. While driving now it runs fantastic about 50% of the time, the other 50% it sputters bad and hesitates under acceleration and has no power. It runs great or bad, no inbetween, like filpping a switch on and off.When its running bad it seems to be way rich, can smell the gas. Only code I get noe is 41 (too lean) I disconnected the 02 sens and ran great for a 30-40 mins while driving but returned to the same intermittent problem. I will replace the 02 sensor tomorrow but I get the feeling it will help but not fix it.
The other thing I can't figure out is that I have to set the base timing to about 32 degrees for it to run good. I've checked the cam timing and already pulled the distributor and set #1 to TDC, it was more than that before I pulled the dist. Found a paint mark on the cover at about 32deg. from a previous owner, I guess thats where it runs good but I can't see why (it is much better set there)
Any insight would be greatly appreciated, it has about wore me out.
Thanks
PS: Already cut off the cat. and it has much more power now when it runs good |
