[VR V6] help, engine lamp on, no power

[nathanVY]

It seems this problem is getting progressively worse, a few weeks ago the engine light would flash or stay on for a minute or two after i'd been driving a bit hard. Sometimes it would stay on and turning the engine on and off would fix it.

Just today it was getting driven pretty hard, all good but 5 minutes down the road the engine lamp comes on and all the power is gone, only like 2nd gear or something. Pulled over, turned the car off for 5 minutes and she's good to go.

What's the deal? What is going to break in my car? I'd like to get it fixed before it becomes a bigger problem, I'm sure the engines can take more of a beating than I give them so there must be a sensor or something buggered (I don't drive THAT hard).

thoughts/ideas/comments/queries?

tried checking your error codes? the engine warning light doesnt come on for no reason!
This will tell you what the problem is.

I did check them a while ago and got code 33, will check again as I've reset the computer a few times.

 

[westbad]

code 33 will be the map sensor

 

[nathanVY]

yeah, should I just replace it? new one? or is wrecker one ok?

edit: of course this is pending another error code check to confirm code 33, which I will do in the morning

i always use new sensors, why take the chance with a 2nd hand one that could be no better than yours??

I would do another check and find out what the fault is for sure 1st.

The loss of power indicates you are in Limp Home Mode which usually comes on when the transmission has a fault. Seeing as you say you were driving "pretty hard" when it happened I'd also lean towards the problem being transmission.
Anyway, do the codes test again as westbad suggests.

hako - interesting, I know it needs a service, maybe it just got too hot and cut sick.

got error codes 45 and 24.

cars done 225kms, its sound has changed in the last week or so exhaust is chugging on idle.

are there any guides on here on how to replace o2/mat sensors?
