My Altima 2K2 is just back from where I changed its camshaft

My Altima 2K2 is just back from where I changed its camshaft, gasket, injector nozzles, oil and filter. Same day, I got P1111. 'Engine idles rough, but drives okay'.P1111 means Intake Valve Timing Circuit Bank1. There is a sensor that controls this, located on the cylinder head that could be defective, but owing to the type of repair just carried out, the ignition timing could be advanced or retarded. Have the technician run a data stream on the ignition timing of the vehicle and check the timing"ponents properly.

I bought Rav4 2003 model. Initially, it will not move when gear is selected. Later, as it moves, it makes some sound as if something is holding the gear from engaging. Anytime my mechanic checks, it works for sometimes. What should I do? Akinpelu, You need to have a diagnostic scan run on the vehicle and the result will help in resolving the issues. Also have the fluid checked for quantity and quality.A Lancashire-based"pany which specialises in green dual fuel engine management technology has signed a trial deal with an unnamed global truck manufacturer.

Now it has signed a deal which could lead to a dual fuel engine for heavy duty vehicles being developed for a market in South East Asia.This is the first programme to be awarded through its cooperation agreement with international engineering group Ricardo signed in September.John Pettitt, chief executive officer of Clean Air Power, said: "It is a pleasure to be announcing a concept study so quickly after entering the cooperation agreement with Ricardo."This is a very exciting but challenging programme which highlights the interest in our technology in major world markets including Asia."Clean Air Power's dual fuel engine uses a diesel fuel injector like a "liquid spark plug", using natural gas with diesel pilot ignition.The firm says natural gas"prises as much as 90 percent of the overall fuel mix, resulting in cleaner and cheaper running costs.The"pany said the aim was to use Clean Air Power's Dual-Fuel"bustion technology to "deliver an advanced dual fuel engine that not only achieves its emissions objective but also reduces the extent of emissions after-treatment required by the base diesel engine".
