Posted 17/03/09 01:48 AM Share Posted 17/03/09 01:48 AM Im abit puzzled about this issue im having in the xr6.. 99% of the times I turn it on, the revs will shoot up to 1500 then drop to under 500 to a point where the car is shaking and about to turn off (it has actually turned off a few times after ignition)also, after abit of a thrashing once I come to a stationary point, the revs will drop to a point where she's about to turn off.any ideas to what the problem may be caused by?the car also does the same thing some times when I turn on the a/c.this is really bugging me 'cause the car is running like crap 1 Link to comment Share on other sites More sharing options...

Its only since being tuned but. No idea why unfortunately. 97% of the time it starts and runs perfectly but just on random occasions it will do those exact symptoms..... weird Edited 17/03/09 02:07 AM by exarsixturbo Link to comment Share on other sites More sharing options...

When you have cleaned the TB. With the car idling go around each joint in the intake tract and the tb mounting gasket/manifold gasket ( the one between the upper and lower manifolds) and the manifold to head gaskets and spray each join. If the car coughs and stumbles when you spray the join with TB cleaner theres a fair chance theres and airleak there. Link to comment Share on other sites More sharing options...

Failing all what you have done, this sounds like a classic case of TPS packing it in.But before going out and getting a replacement TPS, let me know your build date first and also check your fuel regulator for blockages.

I got no clue on the SIDO but the build info is: BA MK2 - 05/05 - what info can you gather from that?I've reset the TPS also but obviously you mean it’s actually crapping itself. I'll have to have a squiz at the regulator. Thank you sir! Link to comment Share on other sites More sharing options...

Completely different manufacturer of the TPS.I've had a heap of BA's that start showing your symptons and sure enough the TPS is giving faulty readings. I usually change to the later type. I'll post a picture showing the two different units. Most obvious difference between the two, is you'll notice the housing of the BA one is slightly larger compared to a the later as fitted to BF.Which procedure did you use to recalibrate the TPS?

So a new one off a BF should fix it then? Will it still fit on the old plug considering the housing is slightly larger or that doesn't matter?
