Check engine light on chevy s10 pick up will come

The check engine light on my chevy s10 pickup comes on & blinks when going up hills, then go out. Now it just stays on all the time! My Mechanic said the diagnostic computer said I needed a tune up, so I did have the full tune-up. The same problem is presenting itself again.

    No. Its never down on the oil... But light only comes on & stays on for a few minutes after climbing a hill. The computer says its arcing.. any suggestions?

    yes it did quit after the tune up for a few days or so. But it started doing it again, It only comes on when I am climbing a hill & stays on a few minutes. So frustrating!!

    Thanks for the suggestions. It cost me an arm & 2 legs for the tune up, and it hasn't solved the problem! The spark plugs do not appear to be loose... This is so frustrating.. Do you know what they meant by ?arc(k)ing? as a computer diagnosis?

    Is the air conditioner on. If so try turning it off. I was pulling a trailer and experienced the problem. It went away when I shut off the ac.

Have you had to add oil? The fact that it comes on going up hill would suggest it's the oil level.

    Did it quit for a while after the tune up?

    Maybe try checking the spark plug wires. That was likely the problem in the first place. Just make sure none came loose.

    Unless they meant the plug wires were screwed, and spark was jumping... i really couldn't tell you. Give them a call.

I got a 1987 chevy s10 pick up truck 2 wheel drive v6 2.8l my transmission is not passing 1st gear ?do you know if the kick cable or tv cable needs to be adjusted .

Just about all you can do is, with the engine off, from under the hood open the throttle all the way and check if the TV cable is tight. And check the fluid level, smell if its burnt or look if its brown.

Other causes could be,
Sticky governor
Sticking shift valve
Worn bands

Many years ago my mom's first 4 speed automatic was a 84 S10 2.8 2wd. She did not know it was a 4 speed and the indicator was broke so she counted the clicks to find drive. She was driving in the hills in over drive and all the downshifting was too much for it (should have driven in hills in 3rd gear). After that the transmission would not shift out of second gear.

The reverse ligths on my mom's S-10 pick up won't come on.

I'm guessing you checked the bulbs. test the reverse light switch. Should be found on the drivers side of the transmission. Should have power leaving it when the truck is in reverse.
