Have Jeep Questions? Ask a Jeep Repair Expert for Answers
Hello and welcome! My name isCustomerand I can assist you with your question. What has been replaced for this already?
So was the fuel pump replaced?
Excellent! So what is the fuel pressure under a load?
Right, I understand. Of course they are going to say that. What is the engine vacuum at?
So did they check for plugged exhaust?
Ok, have them check engine vacuum at idle and under load (or at 2000 RPM) and let me know. Also, have them take a oxygen sensor reading UNDER A LOAD. Let me know.
Hello! Sorry for the delay! Just got home from work. What were the readings of the tests I was inquiring about?
Ok, but you still have not answered my question.
They need to look closer. Do they know if the engine is running lean or rich under a load?
There ya go! You have a fuel delivery problem.
What sensors were replaced? Please list ALL OF THEM THAT WERE REPLACED
Were the injectors replaced? Maybe you just have bad fuel injectors.
Then how can the engine be running lean under a load?
It sounds like I am not getting all of the information here.
Conflicting/missing information. Something is clearly not adding up.
You might want to call them and speak with them. I need to know if the engine is rich or lean WHEN it bogs down and I need to know the engine vacuum readings at idle and at 2000 rpm.
Also, find out how they installed the distributor. If it is not indexed correctly, it will not run right
No internal combustion engine that is street legal can produce 175 inches of vacuum. You might be talking about compression. However, that is not what I am asking. I need the engine VACUUM READINGS. NOT COMPRESSION READINGS
