You'd have to get a timing light and check the timing for number one cylinder at idle, when the engine is warm and see where it's at.

Yes any auto parts store should carry them.

guys. i need some help off topic. ya'll have been very helpful so maybe you can help with this problem. i was driving home tonight and my oil light came on, as well as, the "SET" light for the cruise control started flashing. i was close to home and driving in a neighborhood so i was only doing about 20 - 25 so i decided to drive home, slowly, listening for knock or ticking. didn't hear any. i made it home and was confused about the problem because i just changed the oil a week ago filling with factory manual prescribed amount. so i put it in the garage and shut it off. turned it back on and oil light stayed on but no more flashing "SET" light. i check oil level and it looks good, so no leaking. my dad knows a thing or two about cars and said it could be a malfunctioning ECU or possibly a bad sensor or something scary, but he doesn't know enough about X's so he said to call our mechanic. i thought i would ask on here first. any ideas?

quick edit, i just washed the truck tonight at a hand wash place and i did blow some water underneath to clean all the salt off the underside. possible i got something wet?

Hmmm if it has oil I would take a look at the oil sender connection. Unplug it and inspect the connector and the terminal on the sender. The sender is located directly behind the oil filter.

yeah but could possibly be the oil pump going bad check that sending unit first as it would be a cheaper fix. check for leaks near that unit as it maybe causing low pressure

thanks for those suggestions. i'll check those first thing in the AM. is it possible i got water in the connection?

also any ideas on the flashing "SET" light?

i'm a little stressed out cause this is our only vehicle in the winter. i garage my tc cause i have a work car but can only use for work.

read those threads. "SET" light is off. I think i got the harness wet. the oil light, however, is still on. I checked the sending unit, no leaks. i'm going to just take it in. i don't have the time or tools to do anything major anyway. hope i didn't jack up the engine by driving it a couple miles......

all the mechanics i use aren't free til friday....so i need to figure this out myself if it's an easy fix. one guy said there's a physical gauge on the oil sender that i could verify if there is oil pressure or not, and thus suggesting an electrical problem (ie bad sensor) but i can't find the gauge on the sender....

You have to remove the idiot light sensor and place a gauge in it's place.
