    1990 honda civic lx check engine
    My '90 civic lx starts & idles fine but aftyer a few minutes. The check engine light comes on & when it shifts (especialy when going up an incline or a quik acceleration) it surges & then loses power about 6-8 times in rapid succession causing a jerking back & forth it allways happens at the shift point this does not occur when the check engine light is not on (automatic trans.) any help?

    . Check for codes.

    . Replace the Ignition Control Module (ICM) and coil inside the distributor. Apply silicone heat transfer grease to the back of the new ICM.

    Service Check Connector (SCC): Reading OBD-I Codes

    When the Check Engine Light (CEL) is on, it will be necessary to locate the 2-pin Service Check Connector (SCC) on OBD-I (pre-1996) Hondas. It is normally located under the dash, approximately 1 inch (2.5cm) from the right kick panel. Take a small screwdriver and carefully pry it from the rubber mount. The other 3-pin connector in the rubber mount is the Data Link Connector (DLC), which should be left alone. Jump the SCC with a paper clip, turn the ignition switch to ON (Position II), and count the number of times, if any, the CEL flashes. Reference a Diagnostic Trouble Code (DTC) chart to identify the code being displayed. The SCC is also jumped, when an induction timing light is used to check engine timing.
