Hi!

I bought a low mileage 1.7 cat two weeks ago, and I've loved it to bits ever since.
It's a 98 1.7 with 105' kms on the clock.
Yesterday while on a fairly long trip I notices idle was high, about 1500 rpm.
It seemed like it was misfiring and was smoking BADLY out the exhaust.
I was afraid pistonrings, valvestem seals or something in that line had given up.
But while revving it it seemed like it cleared it's throat around 3500-4000 rpm and was it's eager little self again.
While taking off from the gas station I'd stopped, I really ripped through the gears and everything seemed normal again, until I reached 5th and returned to cruising speed. Back to the bronchitis symptoms like before. In other words the fault comes and goes.
Plus the fact I noticed it was literally DRINKING petrol, in the range of 2.5-3 litres/10 kms. (8-10 mpg)
What the H*** is going on??
I'm suspecting AFM, TPS or a faulty Lambda, but I'm new to Puma's and trying to disconnect any of the sensors doesn't really change anything..

Any known issues to the Puma's that sound familiar to the problems I have?
Appreciate any help...
 
Ah! And I forgot to meniton, exhaust smells like rotten eggs...
 
Ok, thanks for the heads up.. ;)
Just placed an order for a new/used coilpack..
 
I also bought one of these OBD2 bluetooth readers. Fantastic little gizmo, hooked it up to the kitten this afternoon and went for a spin. (Inexplicably the running like a pig issue disappeared once I got back to town.)

It's showing the following fault codes, copied and pasted from the scorpio owners webpage:
"P0302 Misfire Detected - Cylinder 2"
"P0132 Upstream Heated Oxygen Sensor circuit Voltage High - Bank No. 1"
"P0172 System Too Rich - Bank No. 1"
"P1131 Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Lean - Bank No. 1"
"P1383 Cam Timing Advance is excessive"
