It sounds like you may want to use some cleaner spray, but have possibly never worked on or around the engine. If your '98 P30 is like my '99, the sensor is either accessible by removing the large air filter and housing under the right front wheel well, or by removing the engine cover inside the coach. While your Flair may be different, on our Safari TREK, by far the easiest way to remove the engine "doghouse" is to first remove the passenger seat. It's held by four nuts & lockwashers.
