I have the same problem. When I am on the highway I don't smell the gas fumes but once idling or in stop and go traffic the fumes are awful. The 2003 runs great and there don't seem to be any leaks. I don't know what to think and I know I can't afford a costly repair. Any thoughts on what this is?

An old PARKER'S guide to the Uno known starting faults says: Failed distributor vacuum unit. Two small wires inside distributor break after 8-9 years or 60K-70K miles. Crankshaft position sensor.

Worn out piston rings, or other issues causing low compression.

These additives do work, but they do have a down side. You add it to the fuel and the fluid loosens and shifts the gumming up in the system. What can happen is they free up a lump of 'gum' which moves through the system until it blocks another part of the system. Not always, but when the system is badly 'gummed' a real possible. Best way to clean injectors ...

For every day use diesel are better: diesel cost less (in EU) most modern diesel engines are near to petrol engines as performance diesel engine lasts twice of a petrol engine (ex. petrol makes about 250'000k, dieasel 500'000km petrol engine are simpler (less components) then diesel, so less problems petrol engine is economic only if combined with gas ...

Your first bet is to give it a tune up. That would involve changing the following items: Spark Plugs O2 Sensors (whether codes are present or not) Cleaning the Mass Air Flow (MAF) sensor Cleaning the upper intake tract (using a Seafoam treatment or the like) Reset the learning state of the Engine Control Module (ECM - computer). You do this by unplugging ...

It might be that you need to change your spark plugs.

The octane rating tells you how resistant fuel is to premature detonation, i.e. burning before it's meant to. It's quite a long explanation, depending on how much you already know. The short answer is that high octane fuel allows you to fire the spark plug closer to the optimal point during the compression stroke to allow the engine to perform at its best. ...

For an engine, there is a specific peak pressure that it can withstand, which is limited my the mechanical stress limit of the components of the engine parts. This peak pressure is in direct relation to the compression ratio of the engine and the octane rating of the fuel. The compression ratio of the engine stays constant. With a low Octane rating, there ...

Did you check both fuel pumps? Could one be working and one not. There are two on the 2007 one under the driver’s side and one under the passenger side.

I don't know what that specific button does, but I can tell you what similar buttons in other cars do: they retard your throttle response so that your car feels more sluggish. This means that when you step on the gas, it does not cause the throttle to open quite as much, making your drive smoother and more fuel efficient. Conversely, a "sport" button would ...

The ECON button is not a placebo, though the wording from that specific web page is a bit vague. The key is that the ECON button and the Eco-Assist system are two separate things. According to Honda, pressing the ECON button configures your car to improve mileage at the cost of performance. Turning it off will improve power and reduce mileage, which you ...

You have two separate issues here. First, you have what I would think is leaking valve seals. When you slow down, there is a great amount of vacuum build up inside the intake track. With leaking valve seals, this will pull oil past them and down into the intake track. This gets pulled into your engine when you speed back up and causes the blue smoke. ...

Well after having no luck in trying to resolve the issue myself, we finally took the vehicle in. The technician was able to only get one code after trying to get it to reproduce the issue. Fuel Pressure Sensor fault. We had it replaced, a week latter now and still running strong. The technicians explanation was that the fuel pressure sensor pump starts to ...
