i have 98 lx civic, totally stock, auto tranny slipping on 2nd gear, i drive like an old woman, keeping my RPM below 3k, i changed my fuel filter, oil 40/10, oil filter, air filter, cleaned my injectors and still i get 180MILES PER FULL TANK!!!!!!!! WTF?!!!!

i check my O2 sensor its working fine, i use 90 octane fuel, i have 15" ULTRALITE Atec rims, what more info should i include?!

whats going wrong?! please help, a normal civic should get at least 300MILES per full tank

any cel's?

zenon8890

no, nothing at all.

EK9r!der

have you checked your spark plugs to see if you are running rich? have you checked your timing?

zenon8890

no, actually i dont know how to do that, what color on my spark plugs should i see if it was rich?! and if it was, what is the solution?! about timing issue, how can i know if its still factory tune?!

EK9r!der

to check the timing you going to need a timing gun, and i believe the specs on that d16y7 are 16 degrees some1 correct me if am wrong.

here is a link to check the plugs:

thanks alot, what MPG should i be having in d16y7?!

EK9r!der

ma bad i take that back its supposed to be at 12 degrees, well when i had my 00 hatch no mods, driven carefully i was getting more than 300 miles to the tank. if your car is well mantained i would say at least 29 city 33 highway.

what about my 2nd gear slip

blkcivic99_03

You should be getting at least 300 to a tank (10.9 gal tank, approx. 30 mpg) im out of ideas if its not plugs/wires or timing. Any weird sounds or strong gas smell when driving?

zenon8890

no smell at all, i'll change the wires too

zenon8890

how can i know that my d16y7 is 12 degrees on timing?! i'm changing my rotor and cap on Saturday and i wanna make sure that the dizzy is placed right, i just changed my timing belt too and spark plugs wires and advanced my dizzy a bit.

to tell you the truth,my 92 dx get 170 to 180 a tank.everything seem fine,no smell or cel. many people said change the 02 sensor even if you had no cel.i have not done that yet.u can do that

joelmatt89

you need a timing gun, there should be a mark on your pulley for 12 degrees this link explains it well http://www.c-speedracing.com/howto/timing/timing.php if you do much work on cars at all it is def a good thing to have
