So, car has never skipped a beat. Removed the cardan shaft only to go dyno. Drove fine for 30min. Then every light possible came on. First was battery discharge light, then brake distribution, then all the abs, psm. Car went in limp mode. Brought it home and read the codes. Was just o2 sensors and cats. Erased everything. Went to start the car again and it won't start, just cranks and smells very strong of gas. Just tried to read codes again, none found. What happen?!?!

 

Hooked the shaft back up. Car started and idled fine. Drove it 30 feet and brake distribution came back on. Voltage metered pegged. Battery seems hot to the touch. Soon as I slow down all the lights go back off. Car won't make any boost.

Lost......

 

Weird....All the battery connections tight?

Funny how weird crap goes on when doing something that should be unrelated. DERP.

 

Sounds like over charging/regulator but other issues make that not seem 100% I doubt it would help but try disconnecting battery for about 30min. Check ground in rear engine area and as noted battery connections.

 

Battery is tight and did disconnect it for a while. Car now starts, but same issue. I will add I washed the car a day before this happen. But I never even spray water in the trunk area.

 

Have you checked output of alternator?

 

I agree with the other guys. I'd be looking at the battery and alternator.

 

Nothing yet. To check the output should I pull it and have it tested at auto zone?

Battery is new and voltage has been fine. I noticed with the gauge pegged the battery was hot and the vent hose to it was unloading alot of fluid..
Could this be the voltage regulator ?

 

Yes.

 

^ Agree

 

Pelican parts best place?

 

You can buy new or rebuilt and also just replace regulator, may find one local if in a hurry. If the car has lower miles I would replace regulator if not rebuilt alternator= pelican does have one for around 420.

 

Car has 105k. I bought the regulator. See if that works

 

bro sounds almost like what just happened to me turned out to be a blown MAF which was also what i checked last.

No codes present on my durametric.

Disconnect the MAF if it runs its ur MAF.

Cheers

 

You had voltage pegged on the gauge? The car idles and drives perfect....besides zero boost and flashing cels
