So i originally posted that i was having problems with my ride "check engine light came on throwing code 9 (CYP cylinder sensor) which i still dont know what or how to fix. Anyways i pulled the cap and rotor off and to my surprise the screw that holds the rotor on some how camme out and wreaked all types of damage in the cap.....replaced all components (cap,rotor,screw) my question is that my car still surges and the check engine light is still on i have a chopped distributor which has worked suprising well.
but i will buying a new one on the 2nd. Anyways how do you fix a this problem and is it really a distributor problem i thought that check engine lights came on if it was an emissions problem. not an ignition one just need some clairification.

By having an ignition problem, you can have cylinders start to misfire. A cylinder misfire is an incomplete combustion where some unburnt fuel passes into the exhaust and out your tailpipe.
The screw probably beat up the little sensor wheel as it was turning 3k rpm's. Sounds like you need a new distributor...good luck!

is it obd2? if so ur alternator may have chopped ur crank postion sensor wires located by the main accesory pulley. the plug is just above the alt.

this will cause the ecu to pull timing or fatten up the fuel maps so it will bog and not rev a freely

however there is a cyp trigger in the dizzy as well. but if this is wacked ur car will most likely misfire

im confused my car is obd1 and how can the alternator chop the crank position wire do you mean distributor........

akstunt600

no that reffered only to obd2

in obd2 there is a crank postion sensor located by the the alt. and main pulley

in ur case repacing the dizzy as a whole and then clearing the codes should fix ur problem

oh r u runiing the same comp as before? if so u might have burnt out that part of ur computer. always check wirirng first after u try to rplace ur dizzy

sorry bout that
i have a JDM B16a2 running a chipped P28 ecu using chrome with the OBD2-OBD1 conversion harness .....and yes the car is radomly misfiring you can feel it is this bad to drive at higher rpm its hardly noticible but a lower rpm you can really it

akstunt600

yeah get a whole new dizzy other wise u might have burnt out the cyp area of ur comp doulble check ur external wires nad the jumper harness sometimes the the lil jumper wires can cross
