What will keep giving me this light service engine soon ? It happens at boost/WOT periodicaly. I clean throttlebody with carb cleaner and reset it goes off til next WOT. Thanx! for any info.

 

Check all your vaccum lines. You may have had one get loose or cracked and wfo causes a leak which throws a light.

 

First thing you need to do is get to an Autozone and have your code read. Without knowing what code it's a stab in the dark. Post the code number on here and somebody should be able to offer you some areas to look at.

 

Could be your gasoline brand!
I tried Costco's 93 oct. twice and both times did the Check Engine Light come on at boost. With i.e. Amoco's 93 it's fine

 

have you dissconnected the batt so see if it will erase it...if you have than I would do what MaxTorque02 said.

 

THANX! for info, it has been doing this since Iput the K&N panel in and stock. I know it throws a little oil new even with pre-oiled ones. But thanx I'll will get to the Zone since a new one opened about a mile from me.

 

Make sure you connected your maf connections back up when you changed the filter.

 

Thanx !went to the zone and got a PO125 code it stated low coolant temp (160)thermostat in their now also fuel presure low or loop stuff. thats a generic scan tool but, after that he cleared it. so I'm good to next WOT I guess.I know their was some trucks had problems with fuel pumps well see if I need a new Walpro pump in future. Maybe a tuner will chime in this thread.
