I got it and it places fine even + wirr bolt but engine harness is stuck on bottom.


So alternator wont touch smaller bolt hole.

Longer belt or harness with new location will help.

It's not looking like it's a direct swap:

Seems like attachments are reversed, but if those are same size, you ...

Its 140a model but im happy to know will it fit or will 105a model on newer models fit.

What are differences? Only + wire mount?

I have broken alternator on my 1990 and my friend has 1993 trans sport (3.8 v6) alternator but its on miles away so will someone know will that fit?

Same alternator which fits trans sport fits same age bonneville

Hi

There is metal washer. Does it belong under shock mount nut or under shock mount? I didnt found pics.




My old was rusted and very poor so i didnt check it when i opened it.

Can someone check what int and blm is when revving 4000rpm on idle? Or maf mg count?

Yes i have one wire o2. Ex owner had 10 years ago grounding problems with sensor because one exhaust manifold bolt was missing.

New o2 sensor is coming to me. I just wont believe that new o2 sensor fixes my problem


This car's engine management system is mess and im very much out for that :(


I dont understand why its open loop in hot engine and aometimes not. I understand if there is some "2minutes aster start closed ...

Maf does not effect?

In normal situation i had 120-110 values both. Vacuum of it dropped, it was just test.

It has not been in open loop befote ar warn engine, now it is


So many things are wrong :(


What all causes and things effect blm and int? Sensors etc

I tried to take fuel regulator hose off which richened idle etc. Blm was 105-110 and fine fuel same.

Why fine fuel correction wont try fix it 128 or why stock adjust is all the time rich (only 4000rpm it was lean)

Temp sensor is pretty new and it shows like it should.

New o2 sensor has been in now about 100miles.


Every day when i look thru my homes window and see bonneville in parking slot, i wonder what so bad i have been done that american engineers punish me like this :D

Today measuring and testing. Now car is open loop all the time even its warm. Restart didnt effected or just ecm fuse reset.


What can cause that? No fault codes

Now i have new delphi o2 sensor and i cleaned injectors.

Now o2 volts are 90-900mv in idle. Afr was 13.7 until i pressed gas.

Block learn multiplier was 105 and fine fuel correction 135.

I would not revving the engine with no load that high in idle or park. It's really lean up there BLM of 150+ but I would expect that since there's no load.

The driving video showing the shift seems like the transmission slips or the engine hits a limiter at the top of the shift.

In drive its ...

Which videos?

If the O2 sensors are worn/old it won't be able to adjust the fueling correctly, causing a drop in gas mileage.

Now i have video what car does in acceleration and idle. I have aldl connected on idle when car sputters.

Your opinions about videos? (Aijaa.com links)

Tps adjust did tcc to work smoother!

I must order new 02 and injector o rings.

But can faulty 02 do heavy cutting on engine at higher rpm?

96 SSEi wrote:you have a scantool that pulls o2 volts so diagnose the sensor - not that hard, then check injectors

O2 sensor shows 400-700mv. Not stable.

Tps had ellipse screw holes so i adjusted it. Now 0.45v on idle (no gas) and about 4.5 full throttle. Nothing changed.

Injectors, ecm and o2 sensor are only things that i havent changed or checked :D

Here is new results: car not running, throttle full, Tps 4.06volts. 0.45volts are in 1600rpm when car runs



Engine temp about 100f and then something happened. Before that fuel trims were 128/128. Then 114/132. Target afr ratio was 10seconds on 13.7. Idle was heavier then.

Now i have video what ...
