I changed my plugs and everything and turned the car on and it was real uneven followed by a kindof squeek sound and then a back fire from the exhaust and the intake.. any thoughts? im going to go double check the firing order again..

 

its like a miss actually and a very small backfire when it does it.. i just started it again and it wasnt quite as bad.. could it be something in the computer? when i took the other plugs off one of them wasnt even fully hooked up and another was pretty loose.

 

Are all the plugs currently torqued properly? Confirm that you have the plug wires routed correctly. Also, are you using the correct plugs and did you check the gap before installing?

 

yeah, i double checked the routing on the passenger side and i had 4 and 8 in the wrong spots. it runs so much smoother now... Im still having idle problems while in gear though. when i come to a stop it will drop low then even itself back out after about 4 or 5 seconds(it did this before the plugs). any suggestions? (i have slotted the tps etc. for the correct voltage, now changed the plugs, adjusted throttle blade a little with no real results) could it be the valve lash? the mechanic that did this was a *****.

Im also using TR5's gapped at .035 just to answer the question about the plug gap
