OK I will see what another costs the ntk were not bad on amazon, this side gave me problems removing original had to chase threads on the bung so I may just replace instead of the in and out with the already weak threads, will keep you posted

 

Decided to go new ntk again $50 on amazon, being in the teens I do not want to be messing with this anymore then I have to, hope it fixes the code and tremendous MPG lose

 

Good decision.

 

Yeah been staying under 20* here the crap wire insulation on the rover is super brittle so gonna suck but I am hovering at 8 MPG so hope the o2 fixes that

 

OK heat wave today, in the 30's got the 02 on cleared code, 15 miles no reset so far, old one was black a little from being rich with the TPS issue

On a side note tried to fix the teach lead on the alt, and broke off a stud so took parts from the old one that ran intermittent

1) the current alt. had no tach signal cause the teach connector was cracked on alt , easy fix

2) the old alt. Worked intermittent cause there was a broken connection on a small box in connected to the large batt stud

All fixed now 14.10 volts

Bother were different brand rebuilds and the large metal crescent that the fields were soldered to were different, anyone know if that's the difference between the 2 alt sizes?

 

Glad to hear it's all working out. I have to check my alt to see if I'm getting 14V. It's a Precision rebuilt unit that I tossed on. My original needs rebuilding but it was working well when I swapped it. Couldn't believe how deeply the commutator was grooved by the brushes, felt it was time to rebuild and found a local rebuilder through a buddy.

 

They are real simple wish parts were readily available , I remember I used to rebuild alt. All the time when you could buy the kits off the shelf now they just want you to buy new very sad

 

Hi TomR

Did it turn out to be a bad front(up stream) O2 sensor? I have been battling the p1030 code for the last 2 months and tired of the terrible gas mileage. I replaced the rear(down stream) swapped the new left to right with no success. Now a new O2(bosch) on front passenger. Will swap to front driver today. Been about 3+ years since all 4 new O2s.

 

Bosch are crap, ntk are cheap on amazon, mine is fixed just re replaced that o2 guess it got killed when my head gaskets went? My cats were bad /falling apart so....
