Have Honda Questions? Ask a Honda Repair Expert.
Hi Im David, what year is your civic?
ok. now what was the original problem?
throttle position sensor...did you test it?
IAC...did you clean it?
did you adjust the valves?
no, the valves under the valve covers. very common problems on honda and acuras. not too bad of a job either. will hep power and driveability a lot.
so you had the head sent out and checked?
oh, boy. you need to do a compression test on all 4 cylinders.
you need a compression gauge. do you have one?
ok, you can run to harbor freight and buy a compression test set for very cheap and i will walk you through it. its easy.
absolutely. right here. ill leave it open
you get a compression tester?
do you still need assistance?
let me know when you get it
no. but it will make the combustion chamber smaller.
you can run a bottle of seafoam through it. but you still need to do a compression test.
its probably because your code reader doesnt include all of the possible protocol operating systems.
does it say "no comm"?
check for 12 volts on pin 16 and ground on 4 and 5 of the DLC connector
sorry for the delay, had to watch my Steelers win
wow. can you please re type that...i have no idea what you just said.
alot of times unplugging the egr will not turn the car off.
so you didnt get power on pin 16 of the diagnostic connector?
if you dont have power at pin 16 of the ecu, blowing smoke through the intake is the least of your problems. but you can pull the large vacuum hose off of the brake booster and blow smoke through there.
the battery has nothing to do with it, you need to do a continuity teat of the wire from pin 16 on that connector to the ecu plug where that wire comes from.
the ecu? yes. the exact same number.
when you turn the key to the on positon, does the check engine light come on with all the other lights that come on?
ok before taking it to the dealer, did you take the IAC off and clean it out extremely well?
ok, well im going to open this up to others who may be able to help you. please dont reply back or it will take it off the list. good luck
