i have had this car for about 4-5 months and its ran fine. today out of the blue i am driving home and it goes from riding really good to running like ass. really rough. when i idle it it starts dying.... i checked the oil. its fine.. i checks the oil pressure and its fine... and i checked the temp guage and its even fine... i donno what do to ... what could this be?

thanks

i looked at the spark plug and the one on top in the back was burnt to hell... im gonna be trying to figure it out tomorrow.. anyone have any ideas?

 

well first do a complete tune-up(wires/plugs/oil/fuel filter) the whole nine even the coolant if you want. [[[ ALSO:buy ngk plugs and wires ]]]
then you check for probs.
TPS MAYBE OUTTA WHACK if problem maintains after tune-up
if there is still a prob after the tps which i doubt there will be then post up
hope that was helpful.

also these rotaries go thru plugs like they are goin outta style so maybe every 4-6 months they should be changed unless rode on hard then change them maybe every 2-4 months

 

well... now that i think about it.... you know when you first start and it revs high for the first few seconds... well it starts to rev up and down like there might be a tps sencer .... would the tps sencer make the car run like that then when i go back to try to start it... it wouldnt start... let me know

 

if anyone would be so kind to help me out with a few more suggestions... i would appriciate it... or maybe lend me a hand... i live in brandon. if anyone could talk to me about any ideas please call me at, 813-684-4223 thanks

btw this is a 1988 rx7 se

thanks..

Do what seventhgear said, new plugs and wires is always a good thing.

The TPS sensor /can/ make it rev up and down like that. (it did with my 86 GXL) it's easy to adjust and there's a few writeups on how to do it online.

If it doesnt start it might be flooded.

 

well we did a few tests on the car... its getting spark and its getting fuel... so we went and bought a compression tester... and its getting 80 psi on the front rotor... and the needle doesnt even budge on the back rotor... its got to be the apex seal.
