87 non turbo sitting approx 2 years. Replaced plugs, cleaned fuel lines, replaced fuel filter. Car will start go to 1000 rpm then die. If I hold accelerator to floor it will start and if I play with gas pedal will rev and then it will idle. Car will idle fine but as soon as i give it gas it dies. Like i said if i pump gas pedal i can get it to turn 4000 rpm and it runs smooth, but as soon as i change throttle position it dies again. This is my first rotary car and I am unfamiliar. Any help is appreciated

Disconnect the tps (no I'm not saying drive a car with no tps) and start the engine to see if it responds differently. Sounds like a out of whack tps. As in a open/short in the pot.

Another but not as probable cause might be the fuel cut relay or the micro sw in the afm. You can bypass the sw in the afm by jumpering the yellow fuel check connector near the front of the right hand strut tower. Jumper that plug and see if things change for you. Do only one thing at a time.

im very familiar with ford and gm tps. will this be located in the same area on the throttle body. just want to make sure i'm checking the right sensor

hailers, how do you jumper the wire just to ground??

bmphone

i've done the jumper trick. just use a piece of wire to connect the 2 contacts on the connector. This will cause the fuel pump to run continuously with the key in the on position

cool thanks. hey also hailers your always talking about the initial set coupler where is that isn't it only on 89-91 cars for tps setting?

did you drain the gas tank and refill?? I doubt it'll run on 2 year old gas.

you might have stuck apex seals... That means no compression.

Rotary engines do not do well sitting for long periods of time.

blu gxl.....the 87 models also have a initial set coupler, except its a two prong plug and you jumper the two with a piece of wire. If jumpered it will cutout anything that influences the bac or fuel injectors while idling so when you set your idle there are not any other thing influencing the idle. Just the adjustments you are making. I'll go along and admit the jumper is called out for setting the timing, but frankly its not needed. The ECU in a 86-88 ain't got no memory and if it did it forgot what it was supposed to remember the moment you turn the key off.

Say your setting the idle without the coupler jumpered. If you drop down too far on the idle, the bac's gonna want to adjust it back to 750. That would be one confusing situation. It'd be a yoyo effect. I've never seen the installation of the initial set coupler make squat in a difference when setting the timing. My story and I'm sticking with it to the end.

Oh, I just really read blu gxl........I never use a initial set coupler for setting the tps. Last time I looked the engine should be hot and then the engine is turned off. Key back to on and the light assy installed and tps screw adjusted. No need for a initial set coupler. I work on a 86-87 models and don't from memory seeing any requirement for the initial set coupler. Gadzook! Am I wrong.

Initial set coupler on a 86-88 is on the left side of the engine bay. Near the Lead coil assy. Two prong green plug. Do not confuse with the six prong green plug or YOU'LL BE SOOOOORRRRY!

i drove the car for the first time tonight. Replaced the tps. It runs good at partial throttle but it still will not accept more than 1/4 throttle without bogging.
