Re: teggy bogging out
does it take longer to start cometimes. Like cranks a while before actually running. If not probably not a fuel filter. Then yes sensors will make a car bog. Temperature sensor could be off giving to much gas or not enough. MAf will do the same. I would check sensors first.

So yes, sensors can make an engine completely unable to run properly.

Re: teggy bogging out
i see makes sense lol i shall check them
Sensors are the only connection the ECU has with the engine, so the information the ECU is getting is only as good as the condition the sensors are in. Bad sensors, bad information. Good sensors, good information.
So yes, sensors can make an engine completely unable to run properly.

Re: teggy bogging out
CEL?
I would lean towards bad info to the ecu as well. Doesn't sound like the TPS (would idle like shit). The first thing I would check is your IAT sensor. If its just a little off it will run like shit. Mostly when they start going out I've seen them send back the wrong voltage (0-5v thermistor sensor) and the ecu richens or leans the engine out too much.
Hopefully this helps...

Re: teggy bogging out
I think it's sensor related for this reason. I think even in a warmed up car, it'll run in open-loop for even just a minute. I could very well be wrong.
