Okay,

I own a 93 240 sx/se coupe fast back. Manual transmisson, 154K milage. hAS THE 2.4L DOHC engine. I love my car, i never beat on it, only on occasions which are rare. My car is all stock also. No rice burner stuff. I will try to explain my problem the best i can.

When i first start my car it idles at like 750-1000 rpm and the motor shakes, but after it warms up it idles at 1600rpm and the motor quites shaking. Takes like minute for it to warm up. When i go out to drive and get up to 60 mph and take it out of gear to come to a stop it idles at 1100 when i coast and when i come to a complete stop it goes back to 1600-1700 rpm. Also, when im at a light and going to turn left or right i release the clutch in first gear and move slowly in rpms and i go to shift into second gear and slowly ride up to 3000 rpm to shift again and during that rise in RPM in 2nd gear feels like i loose pressure in my gas pedal, like it boggs and rpms want to fall a little bit. And when im driving down the road at 60 MPH, i've also experienced this problem to, when i first start to feel my car bogg or whatever it does i either take it out of gear and it goes to its regular idle at 1600-1700 RPM. Or i down shift. Which i think i have this problem cause of the Missfire.

------------------------------------------------------------------------------------------Problems: -Spiratic Missfire ( Only when i rev the car up in neutral, i can hear it in the motor )-Drop in RPMS ( Not that bad ) -Idles at 1600 RPMS-Runs Rich

Repair/Replacement Parts

-Valve cover gasket-Distributor Cap-Distributor Rotor-Plugs-Plug Wires-Oil Change-Oil Filter------------------------------Going to Buy these Parts next few days-Fuel Filter -Muffler Can. To help the Air flow More efficent, I have a complete Stock Exhaust now. ----------------------------------------------------------------------------------- Now after i repaired the Cap & Rotor the Missfire got better and not as bad at all, i can barley hear it now. Still Idled the same though.

But, PLEASE HELP ME! I love my car to death, i've been studying about 240's ever since i got one i have read up on them, tons of post over and over.. I would really pay anyone to help me figure this out cause not even a In Town mechanic can figure it out. So to all the 240's Experts I NEED YOUR ADVICE/HELP WHATEVER YOU CAN REPLY WITH I WILL TRY.

Thank you guys.

I WILL SERIOUSLY PAY SOMEONE, I HAVE PAYPAL. IF YOU KNOW THE PROBLEM AND IT FIXES IT I WILL PAY YOU 10 BUCKS THROUGH PAYPAL. I AM THIS SERIOUS.

Clean and adjust your iacv. Check tps voltage and check the manual idle scew on the tb.

^^^ look throught the fsm and find the idle mixture/tps adjustment procedure. then check/adjust your timing. start there
