Check the plugs, then the distributor cap and rotor. My 85 SE was running like **** until I pulled the cap and rotor and then I knew why.

 

Sounds like the 115K miles on the chassis probably means a fuel pump that hasn't been changed in just as long. Replace the fuel filter in the back first. See if that helps. Check the ignitors next as described in your Haynes manual. If you don't have one, get one and then do the test. Try the car. Lastly, replace the pump. It's hard to test them because of a "kill" relay under the dash that won't energize the pump unless the engine is actually physically turning. I think that nonsense started in '81 because my '79s and '80 didn't have one. Right now, it sounds like you have a fuel delivery problem, but the jumping tach is a sure sign the trailing ignitor is getting ready to die... B)

 

5900?! Well there's yer problem. One thing about rotaries is they LOVE to rev! ALL the power is up in the higher RPMS. My car is pretty much a stock 85gs 12a at this point and it pulls REAL strong after 3500 up to 7500+ RPM. When I'm hard accelerating I always try to keep it to 7000-7200 max but she still wants to pull.

I did read it......I understand he's got an automatic...... his car is slow 'cause his auto tranny shifts too soon. I recommend that he convert it to a 5-speed.

 

remember how i asked about putting a stereo in? well i took care of it yesterday...had to run my own damn speaker wire



but with that and 4 new kenwoods, i'm good to go :bigok:

 

hey my cars an auto and it shifts at about 6500rpm (84GSL)

i sure wish it was a 5spd

 

all i can say about the looks of your car is ooohhhh she looks damn good,

 

Ok I been thinking this...You want a faster shift..Ok theres shops here in Tampa that can custom make a torque converter why dont you try to get one made before you to a 5 speed..
