Hi All,
I'm currently troubleshooting an Accord diesel that has an intermittent hesitation when the car is floored or when the engine is under load (for example at 80mph). The hesitation presents itself as if it takes about 1 second for the engine to respond to the throttle. The car has been in with a Honda dealer and they can't find the problem, so it's a bit frustrating.
Now, the ERV and FSV was replaced by Honda (at a horrendous cost) but the problem remains. I stripped out the MAP and IMRC body and it was fully of oily sludge so gave it a good clean up, along with an ECU reset (disconnected power), but still the hesitation remains. Once the 1 second has pass the car pulls like a train.
Also, it's not a clutch/DMF as there's no signs of slippage its just as if the engine need a second to get going! It almost reminds me of the delay with kick-down in an automatic.
Could this be the MAF or TPS?
There's no engine light shown and after the 1 second the engine spins up normally. Not stalling at lower revs either.
