My son and I finally finished our winter project which was to rebuild the water pump which had started leaking last fall. In the end we bought a new pump and finally got it installed several weeks ago. Upon start-up, everything seemed pretty tight and we had no leakage. We took it out for a test drive and all was well. A few days later my son took it out for a drive and he sprang a leak.
We found that one of the small heater hoses at the back of the engine had split open. This of course is the one that is only a few inches long and is under and behind the intake manifold. So once again we disconnected everything and removed the manifold to replace this short piece of hose. When we got everything put back together, we started the car which started right up, but the engine immediately went into race mode as it was hitting a constant 3,500 rpm's.
At first I thought the accelerator was stuck, but upon inspection, it was not. All of the springs up by the carbs are where they should be and the idle screws are almost all the way out as they were before we replaced the hose.
I guessing a vacuum hose is disconnected, but we cannot seem to see anything that is out of place. I'm also surprised that a disconnected hose would result in such a high idle.
As always, your help and assistance will be greatly appreciated.
Thanks! [:)]
