check eng

98 taco with 2.7. I just installed a k&n filter in air box with deck mod a couple day ago,truck suddenly started to sputter and check engine light started to flash,auto zone said mas,ait,misfire # 1. I cleaned sensor's but still have misfire .any ideas??

 

Which sensor(s) did you clean? Did you clean MAS?

 

yes i cleaned the mas.unpluged #1 fuel injector and it didn't chang the sputtering so i think my injector is bad i hope.i unpluged nieboring ones and it realy ran like crap.Going to do compresion test to make sure it's not head gasket.

 

Is it a brand new K&N drop-in filter or did you reoil it?
Also with your deckplate mod...did you you the correct sealant? or use any sealant at all?

 

brand new drop in

 

k well that answers my first question of using to much oil and %^&*$ up the MAS sensor....

 

i cleaned the sensor with MAS cleaner they sold to me at autozone

 

all is good ,clean sensor and replaced #1 injector and it runs great.thx for the reply's
