Toyota Camry Engine Problem
it sounds like the tach in the cluster

That would be the first thought, however I've read about three people on another Toyota forum that had the same problem and replaced the tach to no avail. It sounds like a wiring problem, but one of the other people had it happen and there was no maintenance or part replacements done prior to it happening. There appears to be a surge suppressing capacitor on the ignitor/coil assembly and I'm wondering if that capacitor were to go bad would it cause this type of problem.
Check the grounding circuit at the intake manifolds.
Ensure ignition coil + and - wires are not interchanged.
Which engine do you have? Manual or AT transmission?
Same engine replaced?
Yes the same V6 engine was installed, it was out of a '93 Lexus, it is an automatic transmission. The coil wires cannot be interchanged since they are a keyed plug. All the grounds on the engine were tight.
At the check connector terminal # 19 (Black wire) atttach a tachometer and test if it works.
Which check connector? the one under the hood and the diagnostic connector under the dash are not numbered.
The grounds were all good and tight.
The one underhood. Sorry I could not find any identification diagrms to show you. If you check from rear of DLC, you should see a black wire.
Alternatively you can start from igniter. Terminal # 4, Black wire.
