M.I.L. Light flashes at 4.500 rpm

[Renfield]

Hi there,

on this Day we went out to have some fun with the Cerbera. It is an AJP 4.5 build in 1997.

After about 2h of driving the MIL light flashes around 4.500 rpm and is gone when the rpm is under 4.500.

The Handbook said it is the fuel injection or the emission. Does anyone have a clue? btw: i don't have
the ecu diagnotic due the lag of time, will try to get the ecu diagnostic working soon.

greets, mike

so many reasons - you need the software to diagnose otherwise you will end up changing or tuning some many things.
When were the coil packs last changed?

I changed both coil packs around two weeks ago. maybe i broke some fuel injectors by doing this?

Could then be your leads...what coil packs did you fit?

I used this coil packs: http://www.eurocarparts.com (Part-No. 413545061)
The leads were fine, we tested them before and after the coil pack exchange.
Before: 7 were running, after: all 8 are good. tested with a pulse tool.

The only way to tell what is causing the MIL light to come on is to use the ECU diagnostics. Anything else is just guesswork.

I had something very similar, turned out the alternator was overcharging. Check the voltage output at the battery. Should be 14.6ish volts when running.
