hello new here i have a 97 z28 im getting a couple of codes any help/clues on how to resolve these codes would be great thank you



p1035
p1055
p0336

 

please verify the first 2 codes. Are you sure they aren't p0135 and p0155?

If so, those are O2 sensors which is a quick fix.

As for the p0336, is the car stuttering or acting like the ignition timing is off? If so, that's a crankshaft position sensor

 

sorry yes the are p035 and p055 witch are 02 sensor codes and the car does stumble slightly at idle can you please explain what the quick fix is for the o2 sensors

 

replacing them

if you have the stock exhaust manifolds it's not as easy as those of us who have long tube headers because we can change O2's without lifting the car up.

At your local parts store you will find Bosch O2s but they can order Delco for more $$$. As for me, I use NTK (a division of NGK) and they cost less than Bosch and work just fine.

I run NGK spark plugs and o2 sensors

 

ok maybe someone can figure this one out cause it makes no sense i have a code reader and have cleared the codes a few times before and the light always came back on by the time i backed out of my drive way today i unpluged the maf sensor and pluged it back in while the car is running dont know why but i did i then hooked up the reader to see if it threw a maf code and it did i cleared the codes again but the cel never came back on i drove the car for over an hour and still no cel and she is running much better now im stumped anybody have a clue

 

could be in limp mode and not depending on the sensors. unpluging the maf would make it go to limp mode and run on preset info and not sensor info. it should have went back to closed loop after shutting it off for a time and bringing it back to operating temp.

 

ok i just took a 250 mile round trip to long island and the cel light came on about 175 miles into the trip i hooked up the scanner and the same codes came up the o2 sensor bank 1 position 1 and bank 2 position 1 are these the ones before ar after the cats also on my scanner and the o2 sensors that are giving the codes stay at a steady 85 and the ones are bouncing all over the place in the mid to high 100's is this normal

 

bouncing around is normal, steady is not. its sayin the both 02's on the driver side is not working/reading correctly. need to look at the wiring harness and the 02's

 

ok changed the crank sensor and cel went off by its self right away but it had oil on it is this normal
