94 civic rpm going up and down check all vacum hoses changed throttle body gasket check engine comes on and i scanned it it says code 43 running to lean ok to drive. Checked fuel injectors 12.5v any ideas anybody help would be really appreciated thanks

 

check your throttle position sensor..comon problem

 

yea its probably the TPS. they're like $35 on ebay for a used one or your could try the junk yard, i think they're all the same on 88-00 civics. you can't get one from honda, they'll want you to buy a whole new throttle body which is like $700.

 

You could also check your IACV. The screen can get all shitty-ized. Yes, thats my word.
