Please don’t make be jack up the car and crawl under it today.
How difficult is it to remove the exhaust manifolds on an 88 S-4? You guy’s have got me thinking about adding sensors for each cylinder.

 

Hey daryl you may not have to remove anything except the little plugs on the udersides of the head at each exhaust port they might be clogged with carbon but a lil gum cutter works and then you will have a nice threaded hole to attach your sensors, Stan

 

Thanks for that tip! I will look into that.

 

Not hard at all!! IF - you have hands the size of a 2-year old!
