getting only 177 to the tank..helppp!

[franklin89]

hey im new to this site and i know a lil about cars. i jus got my cb7..(92 accord lx) and wen i fill up the tank which takes 13.5 gallons i am only getting 177 mpt. my car is manual and its mostly city driven since i live in nyc. i put 87 octane and i have changed: plugs, wires, cap, rotor, put a short ram intake and the primary o2 sensor. according to my check engine light it said it was bad and so i changed it. what do you think can be the problem? also my cel doesnt turn off. i changed the sensor and still is on. what can be done about tht?

[cvc7chris]

well you sure the CEL is for the sensor?

have you tried to figure it out?
theres a StIKY somewhere that tells you excatly what it is!
first figure out the CEL!

theres a little square plug thing under the dash under your pasengers side!

and just use a paper clip and stick them in both and then put the key in on
position i belive!

the cel light will blink and follow this diagram below me!
and
a long blink = 10
a short blink = 1
It will repeat after all the codes are done.

4. Compare to this list to see what the problem is:

1 O2A - Oxygen sensor #1
2 O2B - Oxygen sensor #2
3 MAP - manifold absolute pressure sensor
4 CKP - crank position sensor
5 MAP - manifold absolute pressure sensor
6 ECT - water temperature sensor
7 TPS - throttle position sensor
8 TDC - top dead centre sensor
9 CYP - cylinder sensor
10 IAT - intake air temperature sensor
12 EGR - exhaust gas recirculation lift valve
13 BARO - atmospheric pressure sensor
14 IAC (EACV) - idle air control valve
15 Ignition output signal
16 Fuel injectors
17 VSS - speed sensor
19 Automatic transmission lockup control valve
20 Electrical load detector
21 VTEC spool solenoid valve
22 VTEC pressure valve
23 Knock sensor
30 Automatic transmission A signal
31 Automatic transmission B signal
36 traction control found on JDM ecu's
41 Primary oxygen sensor heater
43 Fuel supply system
45 Fuel system too rich or lean
48 LAF - lean air fuel sensor
54 CKF - crank fluctuation sensor
58 TDC sensor #2
61 Primary oxygen sensor
63 Secondary oxygen sensor
65 Secondary oxygen sensor heater
71 random misfire cylinder 1
72 random misfire cylinder 2
73 random misfire cylinder 3
74 random misfire cylinder 4
80 Exhaust Gas Recirculation insufficient flow detected
86 ECT Sensor (Engine Coolant Temperature) circuit range / performance problem
90 Evaporative Emission Control System leak detected in the fuel tank area
91 Fuel Tank Pressure Sensor low input
92 Evaporative Emission Control System insufficient purge flow

anyone correct me if im wrong

[franklin89]

yea i checked it before i changed the old o2 sensor cuz the old one had 3 wires cut. i got code 41..primary o2 sensor heater malfunction. and i changed it and its still on. is there any way to check for current? and what about the gas mileage? does anyone know the problem?

[Losiracer2]

did you do your fuel filter recently? how many miles you have on your car? its supposed to be changed every 4yrs/60K miles.

Also clean out your IACV and EGR, maybe that'll help.

Check your tire pressure, that drains a lot of MPG if its excessively low.

Is your engine struggling in anyway to keep it at speed? if it is you might have a sticking brake caliper.

Anything weird going on w/ your engine? sounds? vibrations? give me more info. If you fixed your O2 sensor than that should take car of the Check engine. but if it's still on, you have something else that's wrong. so do that first. but the other things i mentioned help as well

[franklin89]

i jus bought a new fuel filter like 20 mins ago thinking it might be that. i have 182,xxx on the car. where is the egr valve located? i recently cleaned the iacv. tire pressure is at 30psi. when i check the cel codes it only pops up 41. i was there for lik 10 mins and the same code over and over and over again. the car does vibrate a lil on neutral. i believe its idling at 800-900.

[Losiracer2]

egr is to the left of the fuel rail, kinda looks like it has one of those binder clamp thingy's ontop of it. I believe it's held in by 3 bolts, so just undo that and spray it out w/ carb cleaner.

[Boost_Lee]

did you reset your ecu? disconnect the neg terminal on the battery for 10 mins and pull the ecu fuse under the hood...see if the code still pops up

[johnl]

Dirty injectors? Air filter? Leadfoot?

[TypeG]

what kind of o2 sensor did you put on? i know the bosh aftermarket sensors had the wrong resistance for the lx/dx. later.

[franklin89]

i am going to try the egr valve cleaning tom cuz its too late for me to freeze my ass in the cold lol...umm i tryed to reset the ecu and nothing...disconnect each terminal and then both and take out the ecu fuse and still nothing. i even left it disconnected over night and still.i believe the o2 sensor was from denso but im not sure..kinda threw away the box. i dont have a heavy foot and i got a new short ram intake so i dont think thts the problem. i am also going to try tom at work to "borrow" some lucas fuel injector cleaner from work and hopefully tht fixes it. cuz here in ny to fill her up its almost $50 and it only lasts me 1 week and a half. thnks everyone for all the help..ill get back to everyone tom after work.

o2....fuel system cleaner....fuel filter...injectors...

[Losiracer2]

also there might be a chance your cat. converter is clogged, depending on how bad the fuel is over there.

[MrJinx]

was it one of the bosch universals o2 sensors or did it have a factory plug?

[bcjammerx]

You CAN get a bad brand new O2 sensor btw...

what kind of o2 sensor did you put on? i know the bosh aftermarket sensors had the wrong resistance for the lx/dx. later.

ah dammit...if I'm not buying from the dealership...what brand is recommended? I don't remember if I put a bosh in or not...I don't think I did though...but just in case...which brand?

[franklin89]

hey well after a long stressful day at my job..(auto parts store)..i installed the fuel filter. wow i must say that i had the factory Honda filter and lets just say that wen i took it out it was left in pieces. my o2 sensor is from denso i believe. the harness had the factory plug.unfortunately i cant move my car because my brake master cylinder is defective and yea no brakes. i tryed resetting the ecu and nothing. can anyone else gimme any ideas? i got 2 bottles of lucas fuel injector cleaner to put in there on monday wen i get my car from the shop. i cleaned the egr valve also. umm i guess thts it for now i will keep everyone updated on monday wen i get my car. anything else im missing?.....
