Civic Esi engine sometimes dies..HELP

obiwan

hi there,

hope someone can help, my 1994 model 1.6L electronic injection civic engine (80,000 kms) just dies once in a while (but then it will start again when you restart) so far i have recently done the following at a regular car shop....

-replaced spark plugs
-replaced fuel filter
-replaced leaking engine gaskets
-replaced timing belt and oil seal

i thought everything would be fine but then the SAME problem happened again.....

i have not brought it to the Casa yet because i know they are expensive so i am hoping someone here has had the same experience....

appreciate any comments.....

thanks

it's possible na madumi ang intake, mo nalinis na ba yun? meron kasing air-flow meter yon na nagdedeteriorate ang performance kapag narurumihan, armchair theory lang ha, pero it's possible na kapag madumi ang air flow meter mo, less gas than actual ang nasesense na hangin ng EFI mo at mas kaunting gas din ang iniinject ng injector mo, possible reason why it might die out, air filter ba? napalitan na rin ba? mura lang naman palinis niyang intakes mo sa honda one friend of mine told me that hers was cleaned for 3000 pesos daw yata sa honda..., pacheck mo rin, pero kung sabihin na defective ang computer unit mo, ewan ko lang kung dapat mo paniwalaan yon...

^ A related possibility would be a busted oxygen sensor.

Anyway there's also the possibility your idling engine speed (RPM) is too low. Low idling usually means your engine has the tendency to kill itself when not moving.

baka temp sensor, busted... madalang sakit ng mga ek/eg civics.

This is a common occurence with old EFI engines, could be anywhere from loose wire connections for the sensors (try to zip tie them), dirty sensors, busted sensors, dirty intake plenum (usually causes erratic idle rather than engine stoppage though), old plug wires (heck if you havent changed them it's time to change them already with new OEM ones), to low idle settings. It can also be a case of several causes so the best is to look and strike out each one at a time.

Maraming salamat for the info! I have not brought it yet to the CASA, i am hoping to find a car shop that can do the job (cleaning intakes) since Casa is expensive....can you recommend a good shop?

thanks!

Thanks Sakurai! btw, the engine also died when even when the idling was pretty high....

just let me know also if you know of a good trusted shop

Thank you too Slamm and Bravoexo!

all of you guys are very knowledgeable when it comes to cars, my knowledge is only above average when it comes to the older carbureator cars and i will have to admit that i dont know much about the EFI engines....

I appreciate all of your help, now i know what to say when i find a shop that can fix the problem, i will only go to the Casa as a last resort...

cheers guys!

You can try Speedyfix in Santolan Rd (San Juan, right after Ortigas) as they are pretty adept at Hondas over there.

Well, I guess that's one less thing you can consider for your dying D16 engine.
