"check engine" light on (as usual) and the following codes comes when i checked them on my on-car diagnostics that are NOT in my Haynes ("Paines") manual!

A module, #2 socket

5-4-5
5-5-4
3-1-5

Again, cant find them in the haynes manual but it appears maybe a canister issue...????? who knows...
thanks for any ideas!!!

 

3-1-5: EVAP emission control system.
5-4-5: Misfire - at least one cylinder/catalytic converter damage.
5-5-4: Misfire - #4 cylinder/catalytic converter damage.

MANY thanks! espically the troublecode link!!!!
recent plugs, wires and cap...
canister perhaps
probably converter (would like to just get rid of it!)
odo died 3 years ago at 110000 but wife not a real hi-mile driver..

odd part is that when i hooked the jumper to A 6, i got NO codes...not even 1-1-1.

nice to know where to look for codes now...saved the link!!!
MUCHO thanks!!!

Cool, Yeah the cat is probably bad. I would wait for Tech's response.
Just run a straight pipe if you have no E-laws, or just get a universal cat or Race cat.

good luck

 

The misfire codes just mean you have a misfire. If you run it for a long time like that then it can cause damage to the cat converter.

Did you replace the plugs,cap, rotor and wires with OEM stuff?

 

yep..all stock stuff.. well, i may have got a brass terminal cap and rotor if the orig wasnt!

 

is is a short jump to the downpipe? seems like from reading here a LONG time ago, a larger downpipe is a good mod...seems like a good time to go to that, and maybe a mor-flo cat...recommended cat size if i go up, or even if i dont go up on the downpipe?
many thanks, as usual!

 

Maybe an injector is bad then.
Go with a 3 inch downpipe.

 

I would get that odo fixed so that you would know when to perform scheduled maintenance, especially the timing belt. Retrieve the actual mileage from the ECU; see instructions.

As long as you have the DTC boxes up under the hood ('93-'95).

1. Switch ignition on

2. Connect the fly wire to socket - A7

3. Push button 5 times

4. When LED comes on and stays on, enter code 1-1-1 as follows:
- press the button once when LED is still on
- wait for LED to go out and come on again
- press the button once when LED is still on
- wait for LED to go out and come on again
- press the button once when LED is still on
- read off response, which will be the last three digits of the odometer miles

5. Repeat steps #3-4, but enter code 1-1-2 (that is, press the button twice on the last step); read off the response, which will be the first three digits of the odometer miles. If you have less than 100,000 miles, the first digit will read as 10 blinks.
