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.

Thank you txgreasemonkey, that brings me to the other part of my? How & where do I read the codes from? My '90 civic lx has no plug

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.
