Hi, I disconnected the O2 probe and the car works the same way, nothing strange... I'm afraid the probe must not be right...

Edit: I also bought dashboard lights (motor lights) 12V 1,2W and two uds 12V 3W

:shock:

Hi, I replaced the CO2 probe and the car is doing better, along with the TPS sensor. It was a bit cold and it still backfires a bit if I give it gas hard and then some excess gasoline backfires...

I have put the bulbs of the panel and, surprise, the one with the lights comes on, the first one from the left and the second one, light and lambda...(edit)

I'm going to investigate, but I've already seen that I don't have the relay of the lights that goes down on the pedal, the lights work... so I imagine that it jumps because the relay is not there?

I don't know if I'm wearing a blue belt, I don't think I'm wearing a blue belt...

Thank you very much.

As old as the car is, it is bound to have some air leaks which can be the source of the backfire. I suggest you smoke test the intake and exhaust system. Fix any leaks you find. Keep in mind a lot of .01s add up.

The unconnected cables most likely are options you do not have. Inspect them with a Loupe for scratches on the metal contacts.
Scratches = been used before. No scratches = never been used.

Ok!!!!

in the green book say too: 1-1-3 - Fault in injector (Break in lead. clogged. etc..) tha cables look news... maybe the injector

Throttleswitch; full load setting faufty. possible groundlllg short becouse the TPS sensor is new.

Got a Oscilloscope or or a Logic probe? Probe the signal on each injector.
If it was wiring I would expect misfires also.
A fresh set of remanufactured injectors is not a bad idea, US$50 - US$60 per set.

I checked with a voltmeter the connections 9 and 18 to see the ohmm, I put it in 20 and the result was 003.

Buying the injectors is going to be a good thing.

Thank you, Rick. Let's see if I can get this thing to run smoothly.

If it still has problems, check the air intake hose for cracks. Also check the idle air hoses for cracks and make sure all of the hoses are clamped down securely.

Maybe check the fuel lines under the hood to make sure they're not leaking.
