I would have tried new pLugs and wires and using fuel injection cleaner in the regularly. You could also check to see that the Mass Airflow Sensor was not damaged.

Nissan Altima 2002 when running has no power will run sometimes only 35 sometimes not pats 60 very eratic. When I put in neutral and push the peddal to the floor the engine will not go past 4100 rpms and a lot of nocking noise, rattling comming from the engine. Trouble codes are PO 123, 223, 1102,1122, and 2135. Is this the TPS sensor or the PPS sensor and I need to know terminal to check resistance as this is a Throttle by wire car?


The rattling niose can come from the timing chain as oil pressure holds the chains tight. Some of these engines if let go too long on the oil change and changing tthe oil is all you have to do to fix it. Thinned out oil will make the chain loose ma ... 2002 Nissan Altima

My 2004 Chevy Trailblazer is making a bizaar noise when I start it up. It's starts as a high pitch squeal then drops to a lower pitch squeal then ends in kind of a grind. Thought it was a slipping belt but there's only one belt and it's fine. It runs fine and the noise dies away after the engine settles. It only makes the noise on start up. If you cut off the engine before it settles down - the noise continues, so it doesn't stop with the engine. Seems to be coming from inside the engine itself.

1998 Isuzu 3.5L trooper engine (in 1998 Acura SLX). Old engine had noise. New engine has same noise. Every mechanic with an opinion says that something is not right, but nobody has a tried & true solution. New engine runs fine after about 50k miles, but lifter noise still exists. Would really like to have a quieter engine solution.

Hi, I have a 94 Pajero Nj 2.8TD with a 4M40 engine, and when the engine is revving over 2000, be it in gear or out of gear, there is a tap tap scraping noise which increases in speed with the engine. I have taken it to the mechanics and they have told me it is normal diesel noise. I really don't agree, any ideas? The noise is also slightly worse when the engine is cold, but is still present when hot. Any help muchly appreciated!

The knocking or ticking is going to determine if it is in the top end, lifters, push-rod or rocker arm issue or the bottom end that would include pistons or bearings.If it is a ticking noise, it will more than likely be a valve tra ... 1996 GMC Jimmy

Well, if the low-oil-pressure warning light is on, and the engine is knocking, and there is plenty oil in the crankcase, then the oil pump must not be circulating oil thru the engine. So, I agree -- I think your oil pump is bad. ... 2004 Audi TT

Engine noise I have a 1997 Wrangler 2.5L. When running there is a good bit of noise that appears to be coming from the water pump. The rest of the engine is tight and clean. There are no oil leaks around the main seals and no water leaks around the water pump or shaft. When I take the serpentine belt off and start the engine the noise disappears. The idler pulleys seem to be fine as well. I am thinking the water pump needs to be replaced. What do you think?

I took it to a local pep boys and they said it was severe engine problems. The key to this is that it never made any noise, the check engine light never came on.
