Hey! I have a 1988 too and I've had that same problem and it all came back to one thing. The oxygen sensor on the exhaust manifold. It either needs to be changed or the connection is loose right behind the intake manifold. (Dynamic chamber) Hope this works for ya. It did for me.

Take the engine fuse out while putting your foot to the floor and cranking. You may need to spray a bit of engine starter in before doing this. The reason is that the engine fuse will continue to tell the fuel system to pump in more fuel. By removing the fuse, the fuel system will temporarily stop pumping, but will allow the engine to dry out. As soon as the rotary starts kicking like it will start, push the fuse back in and DO not take your foot off the gas until it completely cleans itself out. Usually takes 2 people to do this, but is a common problem for rotaries.

What cause the engine to run rich and black smoke coming from tail pipe?


hmmm sounds like the fuel pump is more of the issue as its sending too much fuel into the motor making it run rich or the gas that your using is too rich for the motor itself

without asking for more details -- the spark plugs could be bad, the ignition firing is off, the ignition wiring is faulty, the fuel injectors are fouled and no vaporizing the fuel for the plugs to ignite.

You need to check that the spark plugs are in good condition and check the spark (spark should be blue = good, yellow = weak spark ) Is there an engine light on? if the plugs are black this is a rich condition (to much fuel, or fuel not burning) the spark plug wires could be bad, weak ignitor,

P0305 is the generic DTC (Data Trouble Code) for cylinder #5 mis-fire detected, and you have already eliminated the ignition tune-up parts as the problem, the next procedure should be a compression check, at least on the #5 cylinder to rule out the possibility of a mechanical mis-fire. If the compression is good then check the pick-up coil located inside of the distributor for any damage, and there is a possibility that a fuel injector is faulty or has a broken fuel line, and if the upper intake manifold is removed, and the large wire connector and fuel lines replaced back on the fuel injector assembly, then cycling the ignition key off and on several times will show if there is a fuel leak on any of the fuel injector lines, and removing the fuel injector nozzles from the lower intake manifold and then cranking the engine over (have the ignition coil connected but be certain to have the ignition coil high tension wire to the distributor cap grounded) will show if any fuel injectors are not firing or have a plugged up nozzle. The original fuel injector assembly in that vehicle has the actual fuel injector inside of the injector assembly block and the fuel travels through a small plastic tube out to a fuel nozzle attached out on the lower intake manifold for each cylinder, and a replacement fuel injection assembly is made a lot better and will have the fuel injector mounted out from the injector assembly block on the end of a larger heavier plastic tube with covered wires running back along the fuel tube to the injector block. Do you remember what the #5 spark plug looked like when you removed and replaced it and did any of the spark plugs have a black sooty carbon fouling? The #5 cylinder is located at the rear spark plug on the driver side and here is a firing order diagram to assist you. The catalytic converter would not be the suspect and moisture or clear liquid dripping from the tail-pipe is an indication that the catalytic converter is functioning properly, unless coolant or liquid is running out of the tail-pipe, then there might be a faulty intake manifold or cylinder head gasket, and a rotten egg smell is usually caused by poor fuel if the smell is coming from the exhaust, or an over-charging battery condition, (voltage at the battery should be between 14 an 16 volts when the engine is running) and let me know if you require the procedure to remove the upper intake plenum, or if you require any further assistance.

Engine surges, black smoke from tailpipe, and excessive fuel consumption


Hi,black smoke from tail pipe is unburned fuel ( excessive fuel consumption ) so your not firing on all cylinders!!! ( that's where the surging is coming from ) if i recall the 88 model has a carburetor.( not tbi,or injected) but either way its going to be in the spark! start with the easiest/cheapest and work your way up... will be like a #1.bad spark plug wire, or #2.bad plug, #3.bad distributor cap,#4.bad distributor rotor,#5 bad electronic distributor module. will be one or more of those items that's bad.......good luck..yz-maniac

90 rx7 turns over but will not start


it could be many things, no fire or no fuel, replaceing your spark plugs is most likely the leats expensive thing to do and if that doesnt work then there is most likley a problem with the fuel either too much or not enough. rx7s are notorious for flooding and it doesnt take much.
