All new plugs and wires, replaced 1 fuel injector soon to replace the other five. The car only misses during acceleration. Temperature was a factor several months ago, but not any more. Found three vac. leaks, fixed. New fuel filter, she is still missing. Any ideas??????

 

Boost leaks will cause a miss. Have you done a boost leak test?

 

I know the plugs and wires are new, but the question is what did you put in it? Alot of people cut corners in this area and buy what the guys behind the counters sell them. The naturally aspirated R/T's have different needs from the TT's. It has been my experience, especially with the twin turbos(I own 2 1995 Twin Turbos), that you MUST go with the NGK platinums and the OEM wires. I have used aftermarket wires and Bosch plugs and within days, missing occurs on acceleration. (BAD MISSING). I have spent hours trying to figure it out. It seems the Twin Turbos do not like the cheap wires. My opinion is that as boost increases, the ECU will, of course, increase fuel to match the air increase and also the spark will increase to burn it all. When the voltage increase occurs, if the wires can't handle it, it blows holes in the wires and arcs to whatever ground it can find. This can occur anywhere along the wire. Look for little white spots on the wire. That is an indication of arcing and is actually ash. The OEM wires tend to be relatively expensive but the arcing does not occur, and that is why I highly recommend them.

 

I did get NGK platinum plugs, as for the wires they are lifetime warranty wires, I don't see any spots on them to indicate arcing. Another repair that was made(i fogot to mention) was one of the coil packs. It was cracked and replaced.
