I have a 1994 RS and gave it the full tune up and it idle's a little rough, I changed plugs, fuel filter, air filter, wires etc. At idle it runs rough and performance is a little bad, Nothing major. I suspect maybe one of fuel injectors not functioning correctley. Sprayed intake with carb cleaner to no avail. Pulling injectors appears to be a great adventure!!!! Any suggestions before i do so!!! Car has 85,000 and has been well cared for.
It is a V6 which I believe is 305!
I change one at a time and the cars performance remained the same before and after service. The wires are about 1.5 years old with about 30,000 miles on them and after market parts!!
That is shamefull!! But that is what I read, I am having a hard time believing that is the size!! I got it up to 110 on the freeway. I guess that's a miricale! That is why they call it a 3,4 liter ift they told you the actual size no one would buy them!!
It still runs good with good mileage.
