where is this vac line located?

 

99 blazer pulled p1345 code so it could be camshaft or crankshaft position sensor. which do you think it more likely is? the problem is when you crank the blazer it idles at 3000 rpms for a second and then dies. what could this be. i know nothing about cars and my husband isnt use to working on these type of motors. so please help.

 

It might not be either. You really have to diagnose the code.

As far as the high idle, well, we've already discussed that. Time to get your hands dirty.

*Combining the 4 threads you have on this problem* - Please do not double post your problem. One post in one section is all that is necessary.

 

So you have a 99 blazer with a carbed V8 swap maybe?

 

I have Ondemand 5 I can pull up your diagram but need more info on your blazer.
