A 98 is a couple of years away from a 2000.
And if you keep on using starting fluid you may blow it sky high.
Never ever use starting fluid on a plastic intake.
If it blows the shrapnel from the explosion can kill you.
This is a different vechicle and may be a different problem.
Two different problems and two different vechicles on one post will get two or more confusing answers.
Start a new post or thread and some one will help you.
Or if you want the repair flow charts for the two codes here is a good link to All data DIY that will led you right threw them.
