My '98 Z24 2.4L v6 coupe cavalier has some issues.
1) My car idles around 500rpm and never higher unless my foot is on the gas. I've noticed when going through drive-thru's my rpm's will dip while waiting with my foot on the brake. I have also heard what I assume to be the fan kick on once it dips. When the rpm's dip its never lower than 200 rpm and then I feel a little shake or sputter like when a car is about to stall but it doesn't stall, just the fan kicks on.
2) Stalling out once in a very while (when on hills) and never gives off any signal its stalling or stalled other than my power steering shuts off or I just happen to look down and notice. It doesn't shake, rattle, or backfire, it just shuts off like it does with the key.
When driving for about 45-90 min and after I got to where I was going I turned my car off, parked it for a couple hours (1-3 hours on flat/ level ground/at least half tank of gas). When I start my car & I'm coasting down hill or braking down a hill that is within feet of the resting point, it will stall out before I reach the bottom of the hill. It starts up and drives without any issues afterward. The outside temp has been around 85°F(day)/65°-75°F(night), no rain within 24 hrs or since last drive when it has stalled. I didn't really let the car warm up for more than a min since it was fairly warm out. Alternator has been replace within a year or 2, battery isn't more than a couple years old, on time with oil changes and maintenance.
3) Dome light, Dashboard, Head lights, Tail/Brake/Reverse lights Flicker.
If I have my lights on at night I have noticed the exterior lights will flicker when in park with my foot off the petals. If I come to a stop while driving or parking with my foot on the brake its even more noticeable than before. When I park in the garage I can see ALL my exterior lights flickering head/tail/reverse/trunk brake light and its not faint by any means.
The dome light flickers the most drastic when the exterior lights are on and a door is open. If the exterior lights are off it still flickers but not as noticeable. I have turned everything off that could be drawing power (heater/AC/fan/radio) and nothing has reduced or helped.
