Hesitation

Recommended Posts

Hello all. My 1987 GL-10 Turbo 5spd, is having some hesitation issues. I go WOT (even if I am not WOT) and it will feel like it is post detonating...not advancing. I checked the timing it's a 20btdc and codes...it gave me 32..for a bad O2 sensor, I didn't think that o2 sensors did that much, to make the car stumble like this.

Thanks for your time.

The O2 sensor is how your ECM knows what the engine is doing. It's vital to the engine control on a fuel injected engine. Replace it and see if that fixes it.

What Subarian said. The O2 sensor takes readings of your exhaust and tells the computer to compensate if its too rich or too lean. If the O2 is bad it could be telling the computer the wrong thing.

Bosch makes both a specific application for the EA82 and a universal. They're both single-wire unheated sensors. The difference is the terminal on the end of the wire. If you want to splice your old terminal on, you can save some money.

 

Just a little bit of advice- if you use a solderless terminal to splice the wires, put a little bit of grease in the terminal before inserting the wires. It will prevent corrosion and make the joint last much longer. Dielectric grease works best, but any grease, or even vaseline, will work.
