I recently became the owner of a beautiful 1993 300zx non turbo. There were no recorded problems on the CarFax report, and the previous owner swore on his life that it ran perfectly (I'm starting to think someone should run him over). BUT, these past 2 weeks, I've had repeated problems with the engine cutting out at consistently RANDOM times, RPMS, gears, weather, and inclines/declines. i've tried using the product "HEET" to remove any possible air/water pockets in the fuel line and simply, am out of ideas. I'm thinking it's an electrical problem, but like I said : i'm not sure. Please help as soon as you can, for this is my daily freeway driver and I won't feel comfortable driving it to work and school until this problem is fixed.

You could try a simple test and run your engine at night and look to see if there is spark leakage from your spark plug wires. Otherwise, you might get the engine scanned to see if anything turns up. Possibly you'd have to get a mechanic to just tighten and clean all vital electrical connections. You might get lucky. |

Replying to: zgirl (Jul 08, 2006 9:26 am) I don't recall on this car---is there an auxiliary electric cooling fan that is supposed to cut in with the AC on, in addition to the regular fan? You know, 3/4 on the guage isn't necessarily a bad thing, as long as the car isn't overheating. Engines like to run on the hot side. Also have you replaced your radiator cap? Any leak in pressure will drop the boiling point of water/coolant.

Replying to: Mr_Shiftright (Jul 08, 2006 9:58 am) Yes there is an auxiliary fan for the a/c, it comes on & works. And now you mention it, the flusher guy did replace the cap. But running at 3/4, it smells like it's hot, it's close to an overheat... that's just too hot, & why after 6 summers did it run at 3/8 & now it's up there? I know they like to run hotter, but really, that it too hot. Ok, I just had it out & about for 1/2 with the air on, it's at 3/8 ! This doesn't make sense.

Replying to: zgirl (Jul 08, 2006 10:26 am) As for the radiator, often they must be taken out and cleaned chemically or replaced. I think a radiator shop could flow test it and then you have a definitive answer. Generally speaking, if you overheat while at idle, it's an air circulation problem and if you overheat as you drive, it's a water circulation problem.
