Pulsating Idle
Idle bounces from 500 rpm to 1000rpm "only when in gear ". (but not every-time I put the vehicle in gear)
If I release the brake pedal while its doing the pulse thing, it will pull the vehicle along with a bouncy rhythm that matches the revs , up until I accelerate past 1000 rpm.
What Ive tried thus far : Cleaned MAF
Cleaned TB
Cleaned EGR pipe
Replaced TPS
Replaced IACV
Replaced EGRV
Replaced FPR
Replaced FPR vacuum line
Replaced Fuel filter
No dice yet !
Symptoms have progressed into idle hanging up at 2000 rpm after accelerating .
I recently unplugged the pressure switch for the power steering and have not had the Idle hang up again ...Yet .
The idle still continues to pulsate , only when in gear , but not all the time , and it happens more frequently when in reverse .
Intake manifold appears to be in good condition , I will be testing it for leaks .
What,where, else should I be looking ?
