#1856 of 2107 Steady "S" light, sluggish take-off, and acceleration power failure
Mar 16, 2010 (1:11 pm)
I have a 1990 Honda Accord Ex with 262,000 miles. When the engine gets hot, the car tends to have acceleration failure. Pressing the gas pedal decelerate the car and it will not normalize itself until I stop and start driving again. In addition, after long periods of driving the car shuts-off when slowing down to make a right turn. Any idea what the problem (s) could be? My final issue is "S" light that sometimes appears and stays steady without flashing codes. When this happens, the car does not shift automatically unless I disconnect the negative battery connector for 10 seconds and reconnects it. I recently replaced the TCM and it works great for a while until this happens. By the way, this is my third replacement. Once the "S" light is off the car shifts like a baby. Any advise would be appreciated.

I had the same problem with my car not starting. I'm not familiar with cars, and I'm not sure of the technical names for everything.. But, I checked the spark plugs and one had managed to come loose on the other end (not sure what that's called, sorry). I hope this helps!

I have a 1990 Honda accord, and my check engine light keeps coming on. I'm not sure why, and nobody has been able to hook it up and tell me what's going on with it. Could low fluid levels cause it? Also, my car leaks gas, anti-freeze (not sure from where), and power steering fluid from the lines. Any ideas where I could be leaking anti-freeze from and where to replace the leaky lines from the power steering fluid? Thanks =)

You're going to have to find the leaks first, before you replace anything. Try pressure washing it, the run the car for a few minutes. If you still can't find the leak, try driving around the block a few times. As for your check engine light, in the passenger foot well, in the far right corner, dig around and under the carpet. There should be a connection plug. Bridge the points with a bare metal paper clip (I have found you can also jam a pair of pliers in it) and turn the car to the on position (engine not running). The check engine light fill flash a sequence (long blinks indicate the first digit in a two digit number), indicating the problem. If there is more than one there will be a short pause, then the next code will blink. Be sure to double-check that you haven't missed a blink or code, then you can unbridge the connector. Report back with the codes and I or the rest of the forum will tell you what they mean.

I have a 1990 Accord. It has a remanufactured head on it, new pistons rings and rod bearings. Since I got the new head I have noticed a ticking noise (not to high or low pitched)...and it ticks at a rather fast pace. I adjusted the valve tappets to 0.010 on the intake side and 0.012 on the exhaust side and the noise is still there. The noise is bugging me, I am worried that something may be wrong and do not want to push my luck as I just did alot of work to the motor. I have yet to even run if for an extended amount of time because I am a bit paranoid about causing damage to the engine. I am running 10w 30 motor oil (the manual says to run 5w 30 but because of how warm it is here I run the higher starting weight). Also, the sound does not vary from when it is first started to when it is at operating temp. Hopefully someone can help me out. I have searched for someone with this same problem and have yet to find an answer other than adjust the valves to the tolerance that I have already adjusted them to. I have also heard that it could be injectors but they were fine before all the work was done and should not be an issue here. The motor has full compression across all the cylinders and runs/idles steady. If you need any more info just as and I will let you know anything else that may help. Thank You!

Does the tapping speed increase when the engine speed increases? If so, you may have missed a valve tappet. I've adjusted mine three times already, and one or two still tap.

this might be a stretch but it might be a cracked ceramic on one of the spark plugs although it sounds like you're pretty mechanical so this may be an insult rather than a diagnostic...if so, sorry...

I have thought that it could be due to the sparkplugs in some way, I know they need to be changed...There is another light ticking noise that sounds like it may be due to bad gas (because of the length of time the car has been sitting) but that problem will be taken care of...anyways the plugs havent been used much but the condition of the motor put alot on the plugs..Also, I will check the tappets again to see if i may have missed one...hopefully that is just the case...I will let you know of the results tomorrow....thank you for the input.

I have a smiliar issue with the ticking. It is like a tappet noise but the lifters are all set to specs and correct oil is used 5w-20 and I have tried 5w-30 witout any appreciable notice.
It has been his way for 30,000+ miles without any problems so I assume whatever it is must not be too serious or it would have manifested itself by now.
The car runs normal when cold for about 2 minutes and then the tappet noise starts. After another 5 minutes of running it slowly diminishes and then stops entirely.
Both a HONDA dealer and an INDEPENDENT dealer that I trust cannot locate any problem and as long as it is not a mainainence issue I am not concerned.
If anyone in EDMUNDS land has an answer I and others would love to hear about it.

I re-checked to see if the noise was before or after the car got to running temperature and it seems as though it gets slightly louder as the temperature goes up. Also, if the rpms are increased the speed of the tick is increased too...I have seen several videos online of what valve lash in need of adjustment sounds like but my sound is a little bit deeper than the sounds those videos are making, and the speed if the tick is also alot faster. It isn't a rod knock...its def. not that deep of a knocking sound. I have yet to let the car run for a long period of time because I do not want to damage anything if there is something wrong. I am going to readjust the valve lash for a 3rd time, this time based off of the cam and not the actual timing marks...so that way I get a more accurate number. I am hoping that this will take away most of the noise I hear. I know from the way it used to run...it was never that loud...it had a very slight tick, but this is far more noticeable than before. Also, when you take your oil cap off, is there suppose to be some type of air flow out or into the valve cover? It seems like a dumb question for me to ask, but I have no idea if thats normal or not..lol..And thanks to everyone who has given a suggestion(s) so far.
