hello,
i got this rover 45, when it first came in it was low on compression on cylinders 3 & 4 really hard to start and when it did ran like a bag of nails and the cooling fans ran continuously.

Did what i call a routine head gasket.

started up first time lovely, but if it was driven it would juddered along the road and the revs would jump up and down but not cut out.

scanned it found the o2 sensor faulty so replaced, thats fine now.
got the p0500 code VSS. as there was no abs codes i put a crank sensor on it still wouldn't clear.

put a temp sensor on it to just in case that was faulty.
When the fault is happening theres just the on code, but if i let it go on for a while the tps code comes up short to earth, now it that just a code that is triggerd by the fault or could that be the fault?

I'm at a bit of a loss with this one now.

your help would be much appreciated.

regards mike.
