Troubleshooting, rough idle/slight misfire
« on: November 08, 2012, 02:52:00 AM »
Hey guys,
Im new to TC, and ive heard great things about you guys.  Im jovani and I have a 93 capri xr2. Just replaced spark plugs with ngk xi's, new waterpump/belt, new headgasket and valve cover gasket and lastly gates timing belt. Upon starting car and sometimes after driving for thirty minutes my car developes a slight misfire at low speeds from about idle to 30mph. Any ideas on what can cause this issue?.. Please feel free to pm me, email or txt. I greatly appreciate it. Also have a friend who has two storage containers full of parts for na and xr2s.. Message me for details im located in Orlando, Florida

Pull your plugs and see if they all look identical, or something else.

Also check your motor mounts.  Sometimes a shift in the motor position can make an air leak.

ALSO share with me all the unique treasures your friend has in those containers of parts!

Welcome to Team Capri

I'd check the plugs too. Perhaps cracked / broken ceramic causing misfire.
Don't forget to update your steps thru trouble shooting and final fix.
I too am interested in a list of the n/a parts

So my problem still exsist, ive noticed car bogs when I touch tps sensor even jus a hair, I unplugged, turned off car, plygged in,and turn back on. Car ran fine for the day, yesterday, problem came back, I tried doing same steps and nothing happens. Feels like car is in a limp mode, boost is perfect and temp is fine, motor mounts are good. Just wondering if its a timing or spark issue. Btw I just noticed oil leak from distributer, would this cause the issue? No cel or airbag light codes related  ;)  lol .. Btw it only happens between idle to about 30-40 and between mostly 1st n 2nd gear
