Idk what's going on now?
I have a 2000 Volvo s40 1.9t with 151k miles on it and I'm having a problem that I can't seem to figure out, whenever I start the car cold whether it's at night or morning, it kind of shakes a little hard and the CEL blinks I've been revving it up to about 2-2500 Rpms for a few seconds and the blinking stops, I have no clue as to what this could be. My CEL is on because I need to do timing/waterpump but idk what this flashing is SOMEONE PLEASE HELP😭😭

I replaced the plugs and the coils recently, about 5k miles ago and the code I'm getting is crank shaft over retarded, I thought that was timing belt? But I have a question couldn't I just do a cat delete? Would that solve my issue? I don't need the cat honestly.

which specific code did you see? there are codes for both camshaft timing and crankshaft timing. These can be caused by a faulty position sensor (there is both a cam sensor and a crank sensor), a mis-timed engine (either the timing belt is off a notch or the VVT gear is not properly positioned) or a failed VVT gear. None of these codes would point to a fault in the catalytic converter or O2 sensors. The point was failing to correct the fuel/spark problem risks damaging other components.

the 14&15 refer to the camshaft timing - suggesting the cam sensor or the VVT is not functioning properly. the 133 and 313 are saying you have a misfire and a mixture problem (maybe the mixture being off is causing the misfire) and the 107 says the MAP (manifold air pressure sensor) sensor signal is out of range. If the MAP sensor is giving bad data to the ECU, it can cause a mixture issue and in turn the misfire... Since you have both a 14 and 15, I'd be more inclined to suspect the VVT gear or solenoid is sticking than the cam position sensor, but there's plenty of posts on the board regarding VVT issues to read as this is non uncommon on Gen 1 S40s. particularly with older engines that were not maintained regularly. Some posters have reported some success using Seafoam or similar treatments or removed the VVT to try and clean the oil galleys.

question, would the wires also be a problem? Becuase I didn't have enough money to change those... and I'll check the map sensor
