3,8 Bonneville´* plugs wets
Hello to the all. I have problem in the -88 Bonneville (not turbo). The fault code doesn't give. the computer of the exchange. The motor gets too much fuel and wets plugs. No source to the visit.
Is composed where is fault?
I live in Finland and so here has weakly help to this to the problem.

No Bonneville came with a turbo (for your information). Superchargers came out in 92.
Try this technique:

And compare your results to these codes:

If you get no codes other than 12, I would suspect an O2 sensor with your symptoms as the most likely cause.

I don't know very well this model and I thought these to be turbo models already 88. I pursue more camaro
Yes give code 12. o2 censor is not at all!? its perhaps would belong be motor back in the exhaust manifold.
ALDL guidance and in the computer when I look o2 value is 450 , but doesn't change.
I took tps management out and give code to it. I would believe ecm is working and in good condition. ALDL guidance and in the computer when I look o2 value is 450 , but doesn't change.

If the O2 isn't changing or toggling, change it.
They're only good for about 60k miles before they start getting tired, and they rarely throw a code. It is in the top of the rear exhaust manifold. If you don't know how old it is, and you're running rich on fuel, change it.
NO bonneville ever came turbo. Only supercharged, and only from 1992-2003.

But how is possible that not o2 censor be in the exhaust manifold? :? :?:
Is without o2 detector being models? Which colour nose management o2 to the censor would come to go? In these is surely one cable o2 censor.

I'm having a very hard time understanding you.
Are you saying there'* no sensor? It looks like a spark plug, and is mounted in the top of the rear exhaust manifold.

All 1988 models must have an O2 sensor to run correctly.
If the O2 sensor value doesn't change with different engine RPM, replace the O2 sensor.
The O2 sensor is supposed to be in the exhaust manifold.
It is a one wire O2 sensor. The wire is purple. Follow the purple wire on the firewall to the O2 sensor. It is located behind the engine, toward the rear of the car.

I speak little this language, the sorry. please ask if doesn't understand me. Yes I mean, no o2 censor. mere plug its at the place
I search the purple wire. There is certainly diode / difficulty, because 02 is deleted.
Million thanks from advised.
