88 Prelude 88 Honda Prelude 2.0 Si Automatic. After the car warms up, The S3 light blinks constantly, then the check engine light came on. The car boggs down then accelerates and decelerates about 300 rpms at hwy speed. When taking off it struggles with the peddle to the floor. Acts like the transmission is having trouble shifting. The next day, it kept dying out even at highway speeds. Had to put in nuetral when stopping to prevent it from dieing. I found the following codes from the ECU: Code 1 Oxygen content A, Code 2 Oxygen content B, Code 8 TDC position sensor, & Code 17 Vehicle speed sensor. Could a transmission problem cause these codes? Any ideas?
took to the dealer, said the distributer is bad, and may be causing the other issues. The TCM did not show a code for the S3 issue. Bought a used distributer and am looking for a VSS as I am told they are no longer manufactured for 3rd generation preludes due to issues when decelerating.took to the dealer, said the distributer is bad, and may be causing the other issues.

U need to re-timed the engine. Check all four marks going across the two cam pully is lined up with the engine head surface.
Then check the crank pully alignment mark the single notche align to the mark on the timing cover
if your d4 light started flashing, then that means a transmission sensor is failing, which causes your transmission to act funny.ill get back to you with a method on checking them and a list of codes to get you started, but dont go and ask for a new transmission. it might not be necessary.
The transmission's electronic control module is most likely bad I had a 1989 prelude that had the same issue I had to replace the TCM on it after the S3 light came on but my problem was a problem shifting, if you have a electronic speed sensor for the trans. and not a speedometer cable the speed sensor may be bad if you have the cable type change the TCM (transmission control module)
I have a similar problem with the S3 light flashing and the check engine light coming on as well as surging issues. On '88-'91 Preludes the ECU is located under the carpet on the right passenger floorboard. There will be a small flap in the carpet you pull up to see the ECU LED. Turn the key to ACC(radio on, but not started) and follow the directions on the link below. http://mustardcat.brinkster.net/p3g/Documentation/ECUerrorcodes/ECUcodes.htm
hmmm u should check the wires going to the coil to see if there is power, if so its mostlikey the coil, and if the coil seems fine you gotta track father back, do u know about the prelude board? http://www.preludeonline.com/ they probably know something about your issue, sorry for the long responce time, was out on my summer vaction !!
What is the TCM?
