After cruising down highway around 90-100mph to a friends I shut off the car and went in to eat lunch. Came back out and the car wouldn't idle after start-up. Car idles erractically, and sputters at start-up. Started several times and finally got started to run. After running down road through the gears it runs awesome (alittle sputter in 1st gear).



On the highway the car runs excellent, but when you gear down to come to a stop-light or whatever the engine lopes, or is erratic and wants to die



I have checked the sparkplugs and replaced all 4, no effect,same erratic engine performance.

You start pulling off plug wires off the cap one at a time to check the plug/wire, no effect. I have noticed that when you pull a wire off the cap to check it I have a spark comming from the side terminal on the first coil from the front of the engine to the wire boot plugging into the coil. Spark arch very visible. Replace the wire at the cap and the spark arching at the coil dissappears.

I have checked hoses and vacum connections. Haven't found any leaks, but no effect.



I need some advise. I know how to work on vehicles, but these rotary's are different.



Thanks for any suggestions.

 

sounds like you have a vacuum leak.

 

Would the vacum leak be a hose or an intake manifold gasket issue you think?



Do you know of a repair shop that works on rotary RX-7 near Sacramento, CA?

 

There are a few in the bay area about 1.5 hour drive. Specialize in any RX-7

 

be scared of any shops in sac... thats why i know how to work on my own car!
