Ok so the car is running rough again and i checked the fuel pressure and it holds at 41 psi. I just did plugs and wires and none of the wires are burnt.
When i was driving on the freeway going up a hill the car started to stumble. Yesterday i checked all of the injectors and they seem to be pulsing right. The opti is new and the coil.

What i have come to think it could be is improperly gapped plugs. I gapped all of the plugs to .60 because the guy at checker told thats what it was at but then i found out that they are suppose to be gapped at .50. Could that be the problem i plan on taking them out and re gapping it but they have been in there for a good 200 miles.


Should i just buy new ones and would that be the cause of it running like ****. Im thinking of doing a compression test when i pull the plugs back out. What do you guys think any input would be appreciated

 

Remember always check all the fluids, and due to the fact you were driving up hill and then started to stumble, usually its fuel, but if you have a 4l6OE trans check the fluid.

 

Stock gap is .050", by the way.

 

oops thats what i ment thanks for the correction. Also all of the fluids are full and its running really rough.

Would the improper gap be the reason for it running rough?

The way i routed my wires 2 wires touch each other could it be arching between the wires?

Also what is the compression suppose to be for the cylinders?

 

up a hill is high load, and high load is very often an indication of a secondary ignition problem

gap your plugs correctly, and if the issue is still there i would be looking at the plug wires, just because they are not burnt does not mean they are fine.
also, scan it for codes just to be sure

i would not be doing a compression test yet, but the readings should all be relative to eachother

 

What plugs did you install?

 

They are some type of performance model but they are ac delco. Also the wires are taylor 8mm over the valve covers.

 

Were the plugs platinum or non-platinum? What heat range?

 

my educated guess is that these are the problem, mine lasted about a month - and the coil wire lasted only a week

i hear so many problems with these, you best bet to replace them with a set of msd wires (cut to fit) and re use your OVC looms

 

They are platinum rapid fires and i just looked it up and they are supposed to be gapped at .60. Here is the link to what they are http://checkerauto.com/ProductDetail...pe=960&PTSet=A

 

Where can i get the cut to fit or order it from?
