Car smokes @ high RMPs. also sprays soot (almost appears to be oil) @ idle and all RPMs. i need to know how to check the codes on my '94 del sol. i've never learned. if anyone can tell me, i'd appreciate it.

 

Online resources sticky ^^^

 

thanks

 

hey guys, i just ran my codes and here's what i got.

7 - TPS Sensor
41 - Primary O2 Sensor Heater

I know my tps is bad, my rpms used to jump really bad @ idol until the motor warmed up, but i changed it. i'm not worried about that. could my Primary O2 be the cause for the soot @ idle, and smoke @ high rpms? i recently changed out my Catolytic converter... any connection bewtween all this stuff?

 

A bad O2 will cause soot because it's unburned fuel. The ECU sees the car as running really lean because there is no O2 signal so it richens up the air/fuel mixture to compensate. Fixing the O2 problem will both fix your smoking problem and give you better gas mileage.

 

that makes a lot of sense, cuz my milage sux too well, thank you. i will buy a new one, and rewire the mess the previous owner made of the harness for it. i'll let ya know if that works. hey, is $58 a decent price for a new o2?

 

Ones from honda are over $200. You decide.

 

hah, thanks... point taken
