Having problems with your Honda Accord ?

I have a 1993 Honda Accord (auto-matic, cruise control) and recently it started cutting off after about 10-15 minutes on constant driving. I was told that the main-relay may need to be replaced or soddered (bad spelling). I replaced it and the car starts more frequently now, but still cuts off just as much. Another mechanic told me that the distributer is heating up and causing the something electronic (possibly the main relay) to shut the car off. My other problem is that every once in a whi

The distributor must not heat up. If the distributor is really hot, then the distributor must be replaced.\015\012
\015\012Your car is not a PC, you do not know that this is an heating problem. Normally, a car only heating problems are concerning cooling system and oil, and when the car is too hot, it does not shut down, but you will get water and oil temp warning lights.\015\012
\015\012The problem happening when the engine is warm means that this is related to a condition that happens at hot engine. Hot engine will need different air fuel mix, and will use sensors as O2, MAF, AIT etc and powertrain control module in a different way respect to cold engine.\015\012That does not mean the problem is overheating!\015\012Also, Relay is not 'Soddered' , it is just connected.\015\012
\015\012Whoever told you this heating up thing was wrong, and the main relay defective will cause multiple problems from start. \015\012Please if you want to give me the name of the person that suggested you relay and distributor if you want. \015\012
\015\012The way to proceed is different , you need to locate the problem.\015\012
\015\012There are many problems that may cause shut down after a while (have never heard a\015\012
\015\012Test vacuum system and fuel pump using an hand tool gauge like this: Deluxe Vacuum and Fuel Pump Tester.

Place the gauge on vacuum lines to find vacuum leaks.
Use the tool on fuel pump outlet to find out if fuel pump is failing.
If there is nothing in there , use an OBD-II Code Reader to pull out code from ECM (car computer). This will reveal eventual problems with idle air control valve and throttle position sensor ,O2 sensors, MAF and AIT sensors, injection, distribution etc. And will tell you if there is misfire.
Once you do this tests , you will be able to localize the problem.
Fuel pump problems, vacuum leaks, O2 sensors problems can commonly cause idle going down after ten fifteen minutes. Vacuum and idle air control valve are among the most common.
\015\012Best regards.
Your main problem seems to be the distributor by what you have narrated. Sometimes the distributor causes these problems. Even I had similar problem in my Suzuki 800 compact. After the distributor was changed, the problem stopped permanently. It is now almost 60000 miles and it is still going strong. So, try the distributor.
