i have a 1998 4 liter v6 engine. ranger xlt. the engine sounds like nothing it wrong. there is no leaking as i can tell. i checked all trasmission fluid, the engine oil, plus the radiator fluid ,and the power steering fluid. those are all fine. i put on a new belt tensioner because the old one was screwing up 1 week ago. the check engine light came on im gussing about 3 or 4 days after i put the tensioner on. any hints on why it is on?

 

Get the codes scanned....

 

how much mileage

 

+1 we have no idea what could be causing it till you get the code read... any auto parts store should do it for free

 

it has 160,000 miles on it.

 

thanks for the tips looks like i need to get the code read.
