2003LS, V6, 120K miles. I replaced all the plugs, coils, IMT o-rings, valve cover and upper intake gaskets this past weekend. Also had to replace the temp sensor on the drivers side, as it twisted off when I went to put it back it.
After putting it back together, it started right up, had a miss at about 3K (not the rev limiter, GEN2). Very diappointing. I took it out on the highway and it ran fine, accelerated fine, did not appear to have any issues. Both times before (this is my 3rd set of coils) with a bad coil, it would invariably throw the wrench code and set a throttle body code, under heavy acceleration. Brought it home, no miss at 3K.
At first I thought I guessed it was from all the carb cleaner that I used cleaning up the intake to get the oil out. It is possible that some water got on something as it was sitting outside when I worked on it and it did rain, but I covered everything well with plastic before the rain started.
Drove it today and it had a miss when I let OFF the gas and was coasting to a stop sign. Its not impossible to have a new coil bad, but it does not act like it has in the past with a bad coil.
It idles fine so I don't think it is a vacuum leak. Any ideas on what to check would be appreciated.
