I like to work on my on car like everyone here. I recently got the engine light on and the TCS on as well got codes P1399,P0300,P0301,P0302,P0305, I changed th spark plugs to bosh platum +2 and got coil ignition from a used 2001 TL that was involved in a wreck the owner said the car only had about 12k so the coils gotta be good dont know????but i put them on my car but still getting the codes.....can anyone help me...... ooo and one thing the car doesnt take off like usual i can feel the engine shack through the gas pedal

You have misfire 1 2 5 and Randoms. You can mark your coils and move them around and see if the misfires follow the coils. If they dont follow the coils/plugs than your misfires are cylinder specific and you most likely have clogged injectors in those cylinders. Also whens the last time you got gas?

the first problem is the bosch plugs are not appoved for the TL
NGK Iridium are good- only denso or ngk iridium or platinum are approved for a reason
your 99 may be different part number than my 01, so ask the parts place, but take those Bosch out and return - they have a guarantee
I dont care if the parts bok listed it!

The coil misfire is usually 1 coil, so you get a known good one $45 and start at the first cyl the codes say- or start at cyl 1 if you want. Put new coil on- run engine- better? you found problem- not better- take new one and move to next cyl while putting original back on what you just tested
Coils are like lightbulbs- fragile inside andwork perfect one minute and the time time- nothing
You can reset the ECU by disconnecting the battery- that should clear a CEL, may require code reader to clear the stored codes
try seafoam in the intake manifold to clean out buildup and crud
good luck

2nd the spark plug issue. Those bosch don't work with a lot of cars. Go with OEM or the recommendations from the mods here.

Thank you guys for the responce at the moment i been rotating the coils to get the readings to find out weather its the coils or spark plugs if not than it must be the pistons how would i be able to clean or deal with the pistons i did change the oil i used castrol sys but changed back to Q and oil filter... and i put engine cleaner as well but this was after the mifires hoping it would fix it but nothing..
now im just rotating coils.. but any input would help and thanks again for ya reply

ooo and anyone knows where i can get input on rebuilding engines im planning on rebuilding my 99 tl engine and put the pistons from the 2000 tl engine block like i said it was in a wreck one of the motor mounts broke from it so im putting the parts in my engine block and it online had 12k what you guys think ???
