"Invalid RPM Reading" on emissions test?

[Eric the Ricer]

Just failed my emissions due to said invalid rpm reading. The guy didn't explain it too well. I have a 93 coupe with 253,xxx on the clock. Everything else passed but this. The sheet he gave me says "This vehicle cannot be accurately tested due to an invalid rpm reading. The vehicle will not qualify for an emissions inspection pass or waiver."

Any thoughts?

BS ALL THE WAY!!! im not sure how things work in va but do you have any other mods maybe he was just bias against tuners or...(ricers)

Faulty wiring or cluster?? Move to ohio we don't have emissions anymore.

Sounds like the idiot who did your test is a moron.

# Dynamometer - Exhaust emissions are tested while a vehicle operates on a treadmill-like device, called a dynamometer, at 15 mph and 25 mph only. No high-speed testing is performed. This test will be given to most 1981 and newer vehicles with a gross vehicle weight rating up to 8,500 pounds. The test is conducted by the inspector at the local testing facility.
# Two Speed Idle Test - Some vehicles' exhaust emissions are tested while operating at idle and at an engine speed of 2,500 rpm. This test is only for vehicles with a gross vehicle weight rating of 8,501 to 10,000 pounds; and for 1980 and older model year vehicles or other vehicles that, because of size or other mechanical configuration, cannot be accommodated on the dynamometer.

You should only have had to do the 15 and 25mph test.

Failed/Invalid result

An inspection that results in a failed/invalid due to rpm and/or dilution is an inspection that could not be completed accurately due to a vehicle problem encountered when attempting to perform the test.

* Invalid rpm readings may indicate that the vehicle is idling at an excessively high or low engine speed or is unable to maintain a stable rpm or vehicle speed within a required range.
* Invalid dilution readings may indicate an excessive exhaust leak, an air injection system problem (if equipped with this system) or some other vehicle problem which prevents a valid sample of exhaust emissions from being obtained.

Problems causing a "failed/invalid" result must be corrected before a complete inspection resulting in an overall result of "pass," "fail" or "waiver" may be obtained. "Failed/Invalid" tests are chargeable tests, and the owner is then entitled to one free retest within fourteen days of the failed/invalid test at the station that performed the original test.

Does your car idle normally? At the stock RPM?
Is your timing at stock?
Does your car hold RPM at 15 and 25mph?

Thanks! I'll check on all this shortly. I haven't driven the car much at all due to a leaking power steering line. I'll get to work and see what I find out :)
