Car runs like s*#t ! ! ! !
The saga still goes on with the Montego Blue one. I can't understand why
these cars don't like for you to do good things for them. All I did was get the cooling system drained and flushed out for the Evans coolant treatment and the radiator was upgraded to a Koyo, changed the water pump (new gasket on the water pump housing) new thermostat, upper & lower radiator hoses, turbo coolant hoses and a hose on top of the motor (under vacuum chamber). I installed new plugs today and changed out the Pettit ECU to the stock one and it still runs like hell. Rough idle low vacuum (aprox 5to7 hg.) won't take throttle past half way (starts to pop & backfire) the vacuum gauge jumps when it starts missing. I can hear the turbo's spinning up but motor wont take any boost or throttle. I've heard people talk about the limp home mode the ECU goes into but when I checked for error codes nothing ! ! ! so I don't know what's putting it into limp mode (if that's whats happening) also major black smoke out of car, really large clouds of it while trying to get it to take throttle. I guess I'll be reading the book for suggestions. Any help from the experts would be appricated. TIA, JAck

Try clearing the ECU. Disconnect the battery and push the brake pedal for about 20 seconds.
This will clear the entire ECU out. Let us know.

Swapped ECU
I tried clearing the Pettit ECU a couple of times. That didn't work so I took it out and puhe stock one back in and it runs the same. I just can't figure what I could have done to cause this since I only worked on the cooling system.

The MAP sensor is a black plastic matchbox sized item with a nipple for the hose. It is mounted on the firewall in front of the driver.

I have been in the "limp" mode for a week, it sucks. My computer would not show any codes either, I could run to around 2700rpm unless I eased it up slowly. I measured my 0-60 times and it was around 34 seconds. Code 26 or 27 are the metering oil pump which puts the computer in the safe mode. I replaced my MOP today but unfortunatlely it had also fried my computer which I will receive on monday. So you should put a quart of 2-stroke oil in your tank if you have to drive it to add some protection for your rotor seals.
Good Luck getting it fixed,
André

Metering oil pump
How does the computer know if the oil pump is working ???? and if it wasn't wouldn't affert both rotors. Since the oil lines coming off the pump run under neath the water pump housing it's possible I could have pinched one, will have to double check and see (they have sheathing over them) Thanks for the place to look as this is where I was working and didn't do anything else that would make sense.Would pinching one off or maybe having one partialy restricted cause this problem ???? Thanks Andre
