91 RR Classic stalling under load

Haven't checked it yet but is it worth changing the TPS? Doesn't look too hard to change unless you tell me otherwise

Here is a used one for $125

OR can this one be used?

I don't like the look of the old one as it would probably be worse than yours.
The other one is for a Thor engine and the end is completely different so will not mate to the 14CUX spindle.
Check it before doing anything.

Thanks Philip and yes, you never know with second hand parts unless they have come from a known source.

I drove the beast for about 5 Km today. It started first time without the previous hassles, also hesitated much less when power eased off, then reapplied. This does not necessarily mean it is fixed - it seems to get worse after a long run, then stop-start traffic but it certainly seems to have improved.

Coopers are pulling apart a soft-dash where I and other have already scavenged several parts. They will let me know in the morning if the TPS is available.

Cheers

BTW have you put some injector cleaner through it?

Also in my experience the 14CUX does not like the low volatility "summer fuel" much. Everything has to be spot on for the car to run well.


My 2006 Honda Jazz didn't like it much either.

The system was cleaned out pretty thoroughly when the new engine was installed.

Re fuel, good point! I'm running 91 ROM mainly because 95 is hard to get at any reasonable price in Goulburn . Coopers tuned the engine while filled with the 91 but did advise that performance would be better on 95 or higher.

The TPS from that soft dash has gone, but Cooper's are looking for another one

After I changed the fuel pump, there was a definite improvement, It was still a bit hard to start with a very minor lag when applying power.

Because I had to go the Sydney anyway, I took the beast to Graeme Cooper's where they ran more diagnostic tests and found a faulty temperature sensor that was sending intermittent readings to the ECU. The sensor was changed, MAF and timing readjusted - The vehicle now runs the way it should! Definite improvement in power, no stalling and (bit soon to tell for sure) a significant improvement in fuel consumption.

Full marks to Ward & others at GCA for these results
