I bought this Dodge Stealth in DEAD condition very cheap on Tuesday. The owner said it had a bad engine. I think it’s just a little naughty. It had nearly new tires and a nice stereo, so I figured I’d get my money back even if I had to sell it for salvage. First off I put a good battery in it. The old one wouldn’t even allow a jump. It fired right up, but ran poorly. It is full of coolant. There is no steam coming out the exhaust, no bubbles at the filler, and it doesn’t run hot. There is a coil pack on the left (as you stand facing it under the hood) end of the engine. (Actually the right side.) I can pull the individual wires off as it runs, and two of them make little, if any, difference. The coils for those cylinders continue to throw sparks to ground, as do the “good” ones when the plug wires are removed. One of those bad cylinders is on the front. I pulled the front plugs and found the bad one to look wet, probably with gas, although I couldn’t smell it. Cleaning the plug made no difference. The compression on the front three cylinders is even at about 140 PSIg. Cranking with all six plugs in place and the ignition disabled is even. It seems the compression is probably good. Pulling the rear plugs to check compression involves having to pull the intake manifold. I’d rather not have to, but will if I have to change injectors. I THINK that’s probably where we’re going.
The MIL was on, so I tried to read the flashes. I did the ON-OFF-ON-OFF-ON with the switch. The MIL went off, and did not flash for over a minute. Should It take that long? I’ve been spoiled by OBD2 for so long that I forget. When I restarted the engine, the light stayed off for a bit, then came back on again. It did that three times. so I guess that’s not going to tell us anything.
I am suspecting bad injectors, but since it is not a fun job to get at them, is there another way to clean them adequately? Miracle in a can? I don’t have any fancy equipment like a motorvac. It would be nice to hear that there is a simple (read cheap) fix, but as little as I have in this thing I’m willing to spend some money or do some labor if necessary.
