Hello Folks, quick question on this one. My mechanic is also at a dead end and we dont know what else to check. :(

The car may run fine until it reaches hot operating temperatures. After this occurs the car will start to take me for a pony ride. It feels just as if the inyection system is dirty or failing.

Now, here is the interesting part. So far, these are the things that have been done to the car: :surrender:
All 4 new Bosch mechanical inyectors BRAND NEW
New spark plugs
New Bosch Fuel pump
Fresh oil change
Fresh filters
New fuel distribution unit
Fuel pump relay checkup -everything Ok

The mechanic has checked the fuel pressure, and it is good. No problem there...
It would seem the problem is electrical. The only remaining this is to swap the computer from another 190 (that's what he said, I didn't even know the 190 had a computer)

Any thoughts ? ? ? ? Similar issue anyone? ? ?

Sensors

Could be sensors sending a bad input to theECU. Check your temp sensor first, then check others. These sensors contribute to mixture and timing. With those out of wack, it would cause the issues you are describing.

Dontforget to checkwiring tothe sensors as well

Gas cap is ok... sensors on the other hand could be causing the issue. Both the mechanic and myself are pretty confident it'll turn out to be something stupid in the end...

but he's been over the car's engine multiple times troubleshooting here and there...and the car is still jumpy :crybaby2:

Honda logo and sparco sticker should make it right

Thanks for the responses so far..

The intake manifold gaskets and the exhaust bearings are quite interesting ideas that have not been considered

Something like that would allow the mixture to be off at a certain range and would cause the failure...

Very interesting... :rolleyes:
