Hi everyone.
A friend of mine bought an EK4 (96-98) with Skunk2 Tuner Stage3 cams, Skunk2 valve springs, adjustable cam gears, complete exhaust and a mapped P28 ECU.
The plan was to put the car stock again and sell all these mods, so that's what i did. I changed the cams, cam gears, and putted the Stock P2T ECU.
There's where the problems started. On the first start the car was running good but the Check Engine Light was on. I checked all the plugs that I had to take off while replacing cams and they were fine too.
Next the troubleshooting:
The Error codes are 3 (intake manifold pressure), 7(TPS) and 41(oxygen sensor), and now the car can't idle at all, is running very very rich, (spark plugs turn completely black and full of carbon after 5 min of idle) - basically undrivable.
So I plugged again the old mapped P28 and the car runs spot on, with no engine lights!
Is the stock P2T ECU not working properly ? What else can be?
Thanks in advance.
