First up let me say ... this car doesn't have an EGR
Well I drove the Car to the Mechanics on Tuesday, he spent 3¼ hrs on it along with his 2 mechanics every so often whilst it was there.
I was with them and held the Lamp and turned on the Car etc.... so I know they spent all that time on it.
When I drove the Car in ... I had been driving it for approx. 8 mins.... so it wasn't over hot.
The Car drove great... didn't miss a bit whilst in gear ( Auto ) , out of gear give it a Rev and it would faulter every time .
So they checked ...
* MAP , ( they thought readings from MAP were odd. )
* Fuel Pressure and Flow.
* Dizzy and Coil.
* Checked Codes and Info with Scanner. .. (NO CODES )
* After Car got Warm enough to keep turning Thermo Fans on,.... the Car
was hard to get it to Faulter..... If we Placed it into Gear and locked
the Brakes and Loaded the Motor when put out of gear ... It would
Cut and Recover for a 20 secs period and wouldn't do it until Loaded
again as above.
* Test Drove car and it never missed a beat
I drove the Car to the Wreckers and borrowed an EFI Relay (Round one) , a MAP sensor, and an ECU...
Next morning the Car would Faulter Badly in Neutral/Park .
* I Changed the EFI Relay..... No Difference .. replaced Old one .
* I did the same with the MAP ... No Difference .. replaced OLD one.
* Changed the ECU and...... it fixed it
I drove the Car back to the Mechanics and Showed him , Thanked him, and he only Charged me $85 for all he did.
I went back to the Wreckers and paid him $80 for the ECU.
I know this is in Hind Sight ....... But I think a Good Rule would be if there are "NO CODES" and something is wrong... the 1st place to look would be ECU ... this is something we would do when I managed a workshop for a S/H Car Sales yard that I owned with a business partner.
We would have Good ECU for a couple of the Popular Models in a Cupboard in the W/Shop... and if we didn't get a code try the ECU.
Well I am retired now and don't have access to the w/shop.
So if you can get a Wrecker to lend you a part to try ... even if it is tried at the Wreckers place.... it can make life a lot easier.
