I couldnt believe it...has a bad shudder when the RPMs come down past 15k. dont know what Im going to do???

..has a bad shudder when the RPMs come down past 15k. .......

Do you mean 1500rpm?

My new, as of last saturday, '94 Q45 just started having a shudder of its own under 1500rpm today. Except mine has no maintenance history,(as in its never been serviced, not lack of records), .

Mine started just after the tank dropped below half, but hadn't reached the quarter mark on the gauge yet.

Wet or dry compression?

[jmorasch]

dry compression test from what I know. I posted ealier after getting home from picking the car up.they had narrowed it to one cylinder.but stopped by advanced auto to talk to a guy I know there that has a Q.had talked to him a few times before and told him about NICO.he came out and we pulled the clips and unplugged the injector,and it made no diffrence or change in the studder.so Im assuming the injector is the real problem. dry compression would give inacurate readings???

Did you ohm the injector?
