Hey, I want to try and figure out what going on with Lexy.. Brought her to Pep-Boys for an inspection because my stickers just recently expired.
My car is a 1994 ls400.
P.S. : (Please don't ride me too hard for that, I know my FIRST mistake was most likely bringing it to "pep-boys", but I figured if it is just for a state inspection than I could save a few bucks that way...
Well I brought her there and I went and bought a snack slice of pizza across the street and mingled around at the best buy checking out some tv's and laptops only to return to my car that FAILED emissions!!!
The "master mechanic" (ha) said that my hydro carbons were at 157ppm. He said if it was at 150 he might consider letting me slide.
He also said that because my check engine light was on I automaticaly fail anyway (which I firmly believe is bull ****** because my car is pre-OBD 2. I thought that any pre-OBD 2 car could have the CEL on all day and still pass inspection
) I was pretty bummed out because the CEL was OFF the entire ride down there (about 12miles). When I got in my car to drive home the CEL was on but turned off as soon as I got to the edge of the p-boys parking lot. I was like WThecK!!
Anyway, here are the symptoms I have been encountering for the past few weeks of driving the car:
1.) CEL turns on with code 25 (lean).
This mostly occurs when it is cold out
2.) Experiencing electrical issues: dash does not light up when it is cold out and the steering wheel no longer comes out automatically when I start the car. (used to work when I first bought the car back in June)
3.) VERY sluggish low end. Almost NO torque and can not get the wheels to spin. (odd for a V8?)
4.) Transmission acts up on occasion and goes into neutral while I am in drive and on the brakes. If I go from drive to reverse the trans changes gears VERY rough and slams into reverse, In reverse the trans will suddenly leave reverse, go into neutral and then go back to reverse.
I have two thoughts as to the issue:
1.) My capacitors are failing in the ECU and screwing up how the car runs.
2.) The O2 sensors went bad, failed, and are telling the ECU the car is running lean so the ECU is throwing in more gas to compensate for the lean condition that actually does not exist and that made me fail inspection.
The car really does not smell like gas at all and there is no smoke when I drive the car. Only smokes when it get very cold out and really its not smoke just condensation/steam and usually goes away when I rev up the engine or give it some throttle. (note: it is getting cold around here in PA. ) No rotten egg smell and not other signs of running rich. Last time i pulled the plugs they looked pretty clean!
Does anyone have any ideas as to what I can do?
I have 30 days to go back to ***boys and re do emissions for free.
I went online to Digi-Key and Mouser to purchase the capacitors for the ECU and instrument panel. I ordered ONLY the CAP's recommended by LScowboy that had the proper capacitance, ripple current (low ESR), high temp, and voltage ratings. Got all United Chem Com caps. I am very familiar with soldering and have build my own Arduino micro controller boards, and a few of my own home made PCB's (with a laser printer transfer method) so I am very confident in my soldering abilities. I will take some pics and do the capacitor replacement as soon as the shipment gets here from Digi-Key and Mouser. Do you agree that it is probably my capacitors or could it be something else??
(Also just as a fun note.. they tried to get more money out of me by charging me for BOTH the emissions and safety inspection and I had to tell the guy at the check out that they never even did safety for my car since it failed emissions.... at which point he asked the mech and then believed me and only charged me for emissions (42$) ... phht)
