Will idle, but making no power... 700 1988


Hmm, well my Volvo guy suggested a little test to see if it's the AMM, which he thinks it is, so I tried it today...

Start and run the engine, let it idle, and then just slowly try to rev the engine, then do it again but now pull the plug from the AMM just as you start to rev it, if it's builds revs better/quicker once the AMM plug has been pulled, it again suggests that it's at fault.

I tried it, and sure enough it did rev a little easier/quicker when I pulled the AMM plug.
So it look like I'm still looking at AMM failure, which I hope will fix it, as it's a expensive part to replace if it's not...

IPD suggest another small test on their site, although I'm not sure about it because it seems a little inconsistent, but it does seem to almost stall when you plug the AMM back in, but not every time.
Sure would be nice if there was just a straight forward yes or no test result that showed if it was crook or not for sure.
