About to Blow Up my car!!!!!!! Wont work Right!!!

Stang Runner · 06-06-2002, 01:27 PM

Here is what it is doing NOW. Idels Fine when you give it gas MY Air/Fuel Metter goes off the chart Leans out!!!!!!! But it you nail it it runs fine.... here is what I have New on the car.
Both O2's
IAC
tested the ECU
tested the MAP
new Ait Tep sensor
New TPS
Diff Injectros
Re-did all Grounds
No Vac leaks AT ALL.
Timming set to 12
Fuel Pressure is good.

Next Might it be the O2's I have in stalled a Ait Fuel Gauge on them BOTH Cut and spliced the wire......... Might that be it making The O2's not work right.......ThX Guys/Gals for the help I need Info FAST as my Truck Tranny Died today!!!! I need to get the stang going FAST!!! today or in the moring PLEASE help me solve this!!!!!!!! Thx for every thing.

Are you concerned with what the A/F gauge is telling you? Or, is the car not running right?

If it's just the gauge, I wouldn't worry about it. Those A/F gauges are worth a big pile of dog poop if you ask me.

I've got one on my Stang and never look at it any more because it doesn't tell me jack. I've got the Auto Meter gauge.

FWIW my gauge reads all over the place all the time practically. Except when I'm hard into the gas does it read a couple notches into the green (rich).

Hope this helps.

THE CAR IS NOT DRIVEABLE AT ALL!!!!!!!!!

302 LX Eric · 06-06-2002, 03:07 PM

Can you get the car to idle at all without having to give it gas? If not, have you tired adjusting the idle-screw on the TB? What is the TPS reading? .95 is a good bogey to shoot for.

Do you have access to a code scanner? If so, see what codes you are throwing. It should help narrow down the issue and save time/frustration.

Just trying to help.

Stang Runner · 06-06-2002, 03:16 PM

Done It Done It Trows no codes... with the car running or with the car Off As it runs fine at a Idel The Tsp is set to .93
I know you are trying to help If I was EZ I would have had it fixed hehe By now...

The fact that you spliced into the O2 sensors could be a problem. If your A/F meter draws any power, it will be messing up the voltage being sent to the computer. The computer ignors the O2 sensors and creates a rich condition under WOT, which might explain why the car runs OK when it's floored, but not in between. Did it have this driveability problem before the A/R meter was installed?

I would take out your A/F meter. Also, check the vac at the EGR valve. There is a solinoid that adusts the vac flow. If it's not working right, and allowing too much vacuum to the EGR, it will have the effect of leaning out. EGR flow is also turned off under WOT, I believe.

Good Luck.

DRASTiK · 06-06-2002, 05:34 PM

well before you place dynomite in it, give me a call. I'll come get it

Sorry man, I don't have a clue what your problem is, but I have learned that when I'm rushed, I don't accomplish anything, I have to slow down and take my time in order to actuall find what's wrong most of the time.

jimberg · 06-06-2002, 05:52 PM

Whe was the last time that your car was working correctly and what did you change since then? What prompted you to get the A/F meters?

shadowblue89 · 06-06-2002, 05:57 PM

Stang Runner,

your message is confusing. In your original post it says you can idle fine butt your second post it says "THE CAR IS NOT DRIVEABLE AT ALL!!!!!!!!!" Not too sure on that one. This is what I have gathered and would check into first.

When you spliced the O2 wires for A/F gauge did you splice the O2 sensor wires or the harness that it connects too? If you spliced the O2 sensor wires that is going to cause a very bad problem. You should splice into the harness wire.
If you did splice the harness wire did you connect the left and right side together? If you did this will also cause a problem of giving the computer a false reading that will not allow the car to idle or run half throttle correctly.

Hope this helps.

Driveable is driving not Ideling... Sorry I was piss off at the time as My Tranny died today in my truck it has been going out for the last 20K but it went Now........

I have 2 Air/Fuel But I did Spice the O2 it self Where should I put it in at... I have Ordered new O2's will have them in the moring.. That was my thinking I was going to Leave them off for a bit.......The Only cars I have Installed Air/Fuel that the O2 dont matter any how..... my Brother Didnt bother to install a O2 in his car even...I know the Mustang that way....... How shoudl I wire in the Air/Fuel??
THANKX alot !!!!! I will keep a update in the moring but I think that Has to be it!!!!

shadowblue89 · 06-06-2002, 06:28 PM

When I installed my A/F gauge I pulled out that worthless chilton book for the wiring diagrams and ran my wire about 3in from the harness that plugs into the EEC. The O2's have seperate wires that run into the EEC. It was the quickest and cleanest install for A/F gauges that I could think of and it has worked great without a problem.

Since you already have the wires ran down by the O2's I would just splice into the wireharness that plugs into the O2's. This will also help you in the long run for when you have to replace your O2's down the road.

good luck and lets us know how it turns out.

PS.
Try not to get pissed when you work on your car. When you get mad just grab another beer and take a break for a few.

Stang Runner · 06-06-2002, 07:50 PM
