missing an maybe out of time

Did you accidentally mix up some spark plug wires?

I thought I did but I looked an they are correct

I just don't understand ik it starts up fine drives great but at times when I start it up an give it gas to go it doesn't have throttle response an then I have throttle response again an at a light stopped or in park when it idles it idles so low about dieing then jumps up to normal idle but the motor feels like it's missing all over the place but it's only the left side of the motor

Is it possible to install the spider injection to the wrong cylinders?

If the truck is at 22 degrees advanced that is way too much. I don't know the spec for your engine off the top of my head but 10 degrees at idle is more like it.

Well its a 96 chevy blazer is it possible the distrubotor needs relearn cause its a preset distrubotor ones were u can't turn

an spider injector I follow the numbers on each spider to the correct cylinder

@js08016 the timing on my blazer is control by computer u can't turn the distrubotor on my blazer once u set it down an bolt it that's it u have to line the rotor cap up to the 6 with the harmonic balancer on the 2nd notch it has 2 notches

I wish i could turn it by hand but I can't the shaft is square an the bracket that's on it goes in the slot an u just put it in an bolt it down now my old distributor I cut the bracket turn that distributor ever direction an didn't change the idle on the blazer. so would it have to be put on a machine an maybe be relearn then

I can't seem to get any car dealers to look at my blazer due to its not a 02 model an up I'm starting to give up any one els know what I can do I tried turning distributor didn't do any thing took sensors off clean then didn't Chang any thing recheck plug wired an spark plugs all looks good fuel pressure good O2 sensors working but didn't change. could it possible that the distrubotor just needs relearn ?

Timing is pretty much a mechanical issue so I think you need to take another look at the distrubutor.

Well I was told from Don franklin chevy dealer that u can put the distrubotor any way u like it like a tooth off an it should be in time cause the computer controls were DTC is an fires an controls from their but not one mechanic can test it to make sure it's even reading right to correct the firing

I just don't know what sensor is not doing its job

If the computer sets the timing there will be a crank position sensor that tells the computer when to fire the plugs.

One tooth off can really screw up your ignition timing! ;)

But how come the timing don't chain when I turn the distrubotor ? my timing marks on the timing chain are right dead in line

@js08016 so your saying unplug the distrubotor an pull it out an take it 1 tooth back an plug back up. cause right now it's set on the 2nd notch on the crankshaft an the distrubotor is set on 6 what I have seen online it's says it's in time but.

This is how it's set as of right now

Well I don't think a timing light will work like i said before my distributor does not move u can't turn it

All that is line up but some reason still out of time shows 22 advance

timing on idle

Nothing changes when I unplug it the crankshaft it just dies an the cam shaft does nothing when I unplug it like it's not reading any thing

The PCM what I'm thinking too
