ok ive had this problem for some time now cant figure it out ,evryone i ask tells me somethign different, my car is a 87 non turbo, 120,000 on engine, when i first start it up in runs fine , skips once in awhile. i drive it for about 15 minuts normally then it starts acting up , it feels like i have 1 rotar runing and it idles really low and shakes alot when its low, but i bring up the rpms and BAM full power. and if i turn the car off and let it sit for like 10 minuts i start it back up again its fine. thats problem 1 .
problem 2 once in awhile when its damp or just randomly ill be driving and my car will like have a hissy fit and kinda not want to rev past 2 grand at all 1 time it happened i turned off heater and window defroster and it ran fine after that. but all other times i had to drive it home all fudged up slow

if anyone can think of anythign wrong tell me
what ive been told is , that it could be the injectors, the computer could be getting wet, crank angle sensor could be screwed(400 dollar part), bad compression (but it runs fine sometimes), too much oil getting into cylander and stopping spark cuz i do get alil high oil pressure.

i donno how to really check any of that so i let my dad have it and hes gonna check it all but if anyone elts has suggestions to help me out id appretiate it thanks.

 

Sticky side seals? Hows you oil pressure when this is happening? Is it low.

 

check the compression first off. Than I would check your charging system, prob no 2 kind of sounds voltage related

 

ID say it's LEAD COIL related and or the LEAD sparkplug wires. And probably NOT CAS related. By the way, a cas can be had at the wrecker for less than twenty bucks. They are almost bullet proof unless you stick something inside them. Unlikely.

A car running on just the Trail plugs will run ratty and not want to rev very well. Like your car. Also change the LEAD plugs. Just the two LEAD plugs. They are the two lower plugs.

Another slim possibility is that one of the two primary injector plugs is coming loose. You have to remove the dynamic chamber to see those two electrical plugs.

A wet ECU. Not likely.

It could be a electrical problem though. If the alternator or battery is really low, the car will act FUNNY. Next time it acts up, look at your volt meter. It should be well above 12. More like 14volts. Also make sure the battery posts are clean and not making intermittent contact.

Make sure the afm's plug is secure as well as the pressure sensors plug.

There is a free, online fsm available. The link is on this site.

 

my oil pressure all the time is really high like close to maxed out! my dad said alil more pressure is better than none at all, which ones are the primarys the ones under everythign or the ones that i can see?, cuz when i put that motor in we had to snake a flat head screwdriver under the intake and push the wire onto them, took longer to do that than the actual installation of the engine including hookin up everythign elts!!. ill mention this stuff to my dad so he can check it - um i took it to a shop to get the brakes fixed cuz i went to move it one day and i pushed the brake peddle to the floor turnes out i needed to fix the master cylandar so i had them take care of that and they were supposed to check all electricals but they didnt want to mess with the rotory engine. um actually the volt meter was fine at the time of everythign going all messed up. because everythign seemd to work sept the engine lol , i always thoguht the car was flooding itself because i would have no power then id rev it up with clutch in and then go and it would run fine till i let off the gas. thanks for the info!
