Technical Am I getting nearer to heaven?

[Paraman]

My vision of heaven is to sort out a lumpy idle and a flashing orangeEML light.
I started out with a new exhaust as the old one was leaking at the flexible joint and the rear box was shot. Did not improve the uneven tickover. Since I had recently fitted new plugs, leads and coil after a garage suggestion, I bought a newer and better OBD2 scanner (Topdon AL400) and checked the pre and post o2 sensors. Both passed. Still no DTC's though. Checked the MAP sensor in the air intake, cleaned it with a non residue contact spray. Refitted but no better. Bought a new sensor since they are cheap and quick to fit. No better. My mind started to think there might be a blown gasket between 2 adjacent cylinders, so sent off for a pressure tester kit which arrived today. I was relieved to find all cylinder pressures between 244-250 PSI so I guess the head gasket is fine. There is no sign of any oil in the coolant. What next? Could the injectors (around 82000 miles use) give a lumpy tickover but fine as revs mount?? I see it costs around £50 + postage to send them away for cleaning and testing but not much more for the cheaper new injectors.
Or do I give up and phone a good auto elecrician. There can't be much more to check! At least I have a few more useful tools for my other cars!

Not Going anywhere! Phoned the only listed Auto Electrician in Inverness, only to find he only did commercial stuff! Suggested local dealer who is well known for high prices! I will once again remove the air filter and examine the wiring connections to the injectors. wiggle them around whilsh engine running. disconect, spray and reconect if possibble. If nothing works probably the scrap heap after I have removed the brang new exhaust!
Life is really to short at 78 to spend so much time on a car which is, after all, now 12 years old.

The canister valve may have stuck open:

Putting hand over exhaust on tickover was a long business. No great pressure build up and a sad little pouf when hand removed. When wife sat in and raised the revs to around 2k (there is no rev counter on my humble model) the pressure built up quickly and a mighty woosh ensued when hand removed. Also checked for any hissing at the exhaust manifold. Nothing noted.
Having read about other posts on dodgy wiring connections, did find and spray, with detox D5, the connector from one ECU to the coil pack...a 4 in 1 job. Also turned lights off and looked for errant sparks. No joy and no improvement. May have a word, at least, with local Auto electrician, after our Friday walk in town (Inverness)

No pressure build up


Are you sure the CAT isn’t cracked ?

Flashing EML with no error codes use to be a common problem on Punto’s and fixed with a phonic relearn

Not do much on the panda but it does cope up occasionally

What engine do you have?
