Stopped up fuel filter.
Go to one of the many Toyota pickup/Tacoma forums to get worthwhile instructions.
Because either that was not the cause of poor performance or you have multiple problems.
check for tune-up, check maf sensor, check o2 sensors, do a fuel system service.
Check the alternator capacity.
Yes, you can use synthetic engine oil in a 2005 Tacoma.
if the outlet is 20A it's ok on a 15A outlet depends what you what to run it may be too much.
run a wire from battery positive to an inline fuse, then to a switch that you have to install in your dash. from the switch to the lights, then to ground. turn on switch, lights should work.
I feel that the toyota hybrid is awesome I also feel that the nissan Leaf is an awesome electric car to run and will never leave you stranded if you have an outlet near by.
$70 to $120 depending on brand. Buy Interstate MTP-24Ffor about $115 and it will last 7 years! Optima batteries are high performance, but run about $170
The water pump is run off the timing belt. did you have the belt installed by a Toyota certified technician? if not i would definitely check the water pump seals.
No.
