TB45E Knocking when starting ...and other bad performance

Post by irfaanharris » 18 May 2015 20:07

Hello all,

I have replaced my TB45E engine and it has two problems.
I have since switched to only high octone (95)

Problems 1 - when starting tye car in the morning, the engine revs high, and as there is initially low oil pressure, the big end knocks. for 1 second.
I believe it has something to do with fuel dripping from an injector. at night. also happens if vehicle not running for a couple hours.

Problem 2. Pinking, low power on long uphill, and sort of resonating engine sound when decelerating? no exhaust backpressure? or faulty advance / retard?

Problem 3..... where is the Knock sensor - I would like to check if it is 460megaohm. / check wiring.

comments will be most appreciated.

Thx
Faanie

Is the problem not the fuel pump as well.

When I replaced my fuel pump I can still drive uphill in 5th gear.

Hi irfaanharris

Herewith Graham's advice:...

Problem 1: Check basic setting on TPS switch, must be at point 0.50mA. Idle compensation valve must be set to 20%. Distributor must be set to 5 degrees. All must be set when car is at running temperature.

Problem 2: This should sorted by correctly settings for problem 1.

Problem 3: Knock sensor is on the right side of the engine under the intake manifold but a electronic diagnostic test can check if this is faulty.

P.S. All petrol Patrols should be running on the highest octane fuel available in this country or even better put in Octane boost on every tank of fuel.

Thanks, hope this helps. If not, an if you're in the area, bring it in, and I will do these checks for you.
