96 Es300 Looses Power After Warming Up
Posted 27 July 2012 - 09:20 PM
Now the problem is that sometimes when I start the car the tach and speedo do not move at all.
when the car warms up the cel comes on and the car looses power. You can barely keep it running and it pops and stalls and will not move.
After it cools down for about 30-45 mins it runs fine again but only for a short distance. Onc,e it cools down the CEL goes out and there are no saved codes
I just had the car painted and the body shop told me the battery went dead on them several times in 2 weeks. After the first time the needles went dead on the tach and speedo I changed the battery cable ends. I haven't checked the other ends of the connections yet.
I have started the car and have had it running for about an hour with no issues. I have driven it around the block no problems
Checked battery voltage before start and it was 12.4
While running i am getting 13.6-13.7 volts at the battery
After running for 30 mins i have noticed the battery cable ends get hot but if you leave the hood open they cool down enough to touch them. while hot i tightened them both up

However, I am afraid that you are ultimately doomed. The gods have noticed that you spent some $$$ to have her repainted and now that it is looking nice again, little annoying mechanical and electrical issues will plague you. (jk'ing. look for the codes)

Any ideas out there? This thing is driving me crazy

This is just one of those flaky problems that is extremely hard to duplicate.

The problem was the idle being set to low.
Normal rpm is set at around 1500 but mine was bottoming out under 0. Especially when I slowed down from braking.
When I started my car my rpm would barely jump.
It's a really simple fix..
Just as yur Mechanic to turn yur idle control up.
Yu can actually do it yourself no problem.
Hope it helps....Keep me posted

Since I keep hearing that this could be a electrical power related issue i have done the following:
I have tested the battery (it is good)
I have tested the Alternator (it is good)
I have tested the positive cable (it is good)
I have replaced the negative cable. It did not test bad but the advice I have been getting locally is that this sounds like a bad ground.
I have a used ECM coming from EBay that I am going to keep in the car. The next time the car starts acting up I am going to swap the ECMs and see what happens. I havent test driven the car again to since I dont feel I have figured out what caused the problem. Once the ECM arrives I am hitting the road until the problem repeats.
Someone mentioned a sensor on the transmission that could be the source of my won't move in drive but will move just fine in reverse. Anyone know what this sensor is called?

I am picking the car up today I am going to get them to show me where the grounds are. If I start having weird issues again I will start with those first. I started out thinking this was a ground issue and replaced the battery ground and cleaned the contact points for the couple of grounds I saw on top of the engine I just need to go a little further.
Will post after I drive it a couple of days and let everyone know the result.
