I have an intermittent hesitation issue I can't figure out what the problem is. Just yesterday I replaced the fuel filter, pcv valce and did a tune up, replaced everything with new. I was advised it could be a vaccuum leak. I need some advice on probable causes.

 

I did a compression test before putting in the new plugs and everything was good. I am considering replacing my o2 sensor and either the egr gasket or the egr itself but I honestly want to avoid the added costs. I checked my oil and it has broken down considerably and it hasn't been driven more than 50 miles since the last change. I'm going to replace it with a synthetic 10-40 rather than 10-30, unless a thicker oil is recommended?

 

Compression fine, new fuel filter, tune up & pcv valve. So, I'm going to get a egr gasket and check that tomorrow. How should I check for a vacuum leak? where could it come from? If that's not it it might be the clutch i think i'm going to be depressed for a couple days cuz the clutch I knew was on it's way out since I got the truck.

Is any year clutch kit compatible? They used to have some good deals on clutch kits on ebay but go figure now they don't! If so I can use a later model kit I might be able to save alot.

 

try the throttle position sensor lo, not sure how to check it but i'm sure someone here can help you with it or it might be in the FAQ section.

 

thanks man, ill check my manual aswell

 

Ok, a better description would be that it "bogs down" sometimes. My uncle said the timing might be off!!! No one can suggest anything?
