Engine Bucks and Stalls

It starts but when u try to drive it wont go it just bucks and doesnt want to move the fuel pressure is 90 psi the injectors are working and it does have spark the only code is p0172 which is bank 1 rich but have replaced fuel filter/regulator checked lines no kinks

Yes im positive tested everything and changed alot of parts and nothing seems to be helping the code is bank 1 rich please help I dont know what else to do

Also changed crankshaft sensor module and coil packs checked all fuses and still when u try to drive the car it just bucks and doesnt want to move but seems to idle ok unless u force the gas then it dies out like it flooded

Yes I have the old one is gas suppose to come out of all the lines where is the vaccum hose for these regulators put the old one back on and there is no difference just did a check with timing light and there is a skip changed modual and coil packs again or what should I do please help going crazy here

Where can I locate a vaccum line for the fuel is there even one and is there a camshaft sensor in a 98 sl2 what makes it have to high of fuel pressure and how can I check the new modules that I just put in cause it is not firing right on 3 of the 4 cylinders

The code is p0172 when you check the gas pressure at the on position the psi is 48 when you start the car at idle the psi is 90. I replaced the o2 sensor on bank 1 today and still no change.I bought the fuel filter at advanced auto not sure what the brand is or the part number.I ahve also changed the coil packs and module.I cleaned the egr today was plugged but cleaned it anyway just to check. Is there anything else I can be checking I am at a loss no clue what else to do.

Yes the old one also had a fuel pressure of 90 psi all the lines have been checked for kinks and there is none and I just changed the coolant temperature sensor and no change it still stumbling while u try to drive and if u rev the engine while at idle when u get to 4000 rpms it makes the car die

The one I bought was a Purolator part number F65501 from advanced auto parts is there any possibility it could be the map sensor I tested the throttle position sensor and that seemed to be working alright

When I called them they said it was the right one they charged me 50 dollars for it is it suppose to be more like 100 dollars for it with the regulator would the old one I took off have a 90 psi because it was bad they both read the same when I put the old one back on and the car was running fine until about the last 2 weeks then it just wouldnt move I really dont know much about cars do you think that advanced auto took advantage of me because I am a female and sold me the wrong one. If the car is cold I can drive around the block small block about 3 mins then once it starts to warm up is when it starts to buck.I checked the plugs and there not wet is that normal for them to be completly dry.
