The crank sensor is very hard to test. Unlike the other sensors on the motor that can be tested when the motor is not running(even that is iffy). I'd replace the crank sensor at the risk of spending your money. And don't cheap out on it if you decide to replace it. And also do a side by side comparison and make sure whatever brand you buy, is of equal length.

 

i guess i will be going out and buying a crank sensor, a iac and a tps and see what happens. The tps allready tested fine too.

 

Why buy all those sensors? the crank sensor is a shot in the dark to begin with . But that's the one I'd start with.

 

Well after a week of headaches. i finally stumble across the problem.......it was the timing. i had to turn the dist counterclockwise and now it runs good. So simple. Thank you for all the help.

 

OK. Now for the bad news......turning the distributor changes fuel sync. Need to take it in and get that set.

My guess is that when changing plug wires they were off by 1 which is why turning disty it runs better.

 

Think the wires were off by just 1 spot in the first place? should i put the dist back and re run the wires?

what happens if it doesn't get re synced....what do you think the cost would be to sync it?

 

The sensor in the distributor tells the PCM which injector it should fire when. If it's off, the engine will NOT run as good as it should. If it's off far enough, the engine won't run at all.......

Number one is marked on the cap, and there is a procedure for setting base timing in the FSM. Might wanna go thru that, then take it someplace that has the ability to set fuel sync. Shouldn't cost more than an hours labor.

 

awesome thanks

 

Something else to consider.

If you are replacing spark plugs more frequently than normal, get a compression guage and check your compression. If its getting worse when warm, the head gaskets can be expanding a little causing a slight leak. In my case, after my motor got warm I had a slight miss that would come and go from water drops dropping on to my spark plugs and my piston head from a head gasket leak on my number 1 and 2 piston. I didn't think much of it at all because very light miss, I had changed all the electrical and it seemed to have corrected it because I had new spark plugs. About 1 month after changing everything those water drops finally blew a hole through my number one piston causing catastrophic failure. Just a thought.

 

Where were the water drops coming from?
