Does it matter if I use a 535 rear upstream 02 sensor on my 335 single turbo only difference I can see is the 535 is 100 mm shorter and 40 dollars cheaper.
I don’t see how if it’s the same sensor he’s cutting the wrong corners ... am I missing something here
Yeah my understanding is that they are both for the rear turbo bank 2 . One is 1100 mm on length(535) the other 1200mm in length (335). Not trying to cut corners just tryna save a couple bucks since this car has been draining my wallet and hasn't moved off of jackstands for a month.I don’t see how if it’s the same sensor he’s cutting the wrong corners ... am I missing something here?
Do you think these will work on DOC race manifold? can they handle the heat? i change o2 sensors every month lol using bosch!You can use any Ls4.9 O2 sensor. As long as the cable is long enough.
Try some gm cars they are cheaper.
mileage on your plugs? Could be those coilpacks if they haven't been replaced in a while. Upgrading to PR coils saved me a bunch of coil headaches that I used to get with this engine all the time. It sounds like a spark issue. What cylinders are misfiring?Any help guys ? Zero misfires or anything like that. Brand new Bosch 02 sensors. Can it be my coilpacks? Thats what I'm thinking since they were an issue when my friend had a misfire I let him try them , they made his care run worse.
Ahh I see, were the plugs wet from fuel by chance? How many cylinders are misfiring?I pulled the plugs out this morning to see what they look like there not good at all for having less than 500 miles on them but regardless I don't think thats my issue. The only difference from this new car i built to my last car is I have a jb4 and port injection now. I unplugged cylinder 2 coilpack to see how it would run and there's no difference. I unplug cylinder 1 and the car dies . Not really sure whats going on , I guess I'm gonna buy another mhd license for this new vin number of mine and rip out the jb4. Literally have zero clue left what to do. Terry at bms says I should take it to a good mechanic lol. I'd like to know what this other good mechanic would do. I've tried multiple sets of new pencil style coils nothing changes I don't think my issue is in the hardware itself everything is brand new and seems to work on other peoples cars when I try it on theres.
