What performance results would fixing these symptoms give for my car?
So my car is an 2003 Honda Element 4 speed auto awd. Sometimes when I take off the line my truck accelerates quicker than it does at other times meaning sometimes when I takeoff from a light stop, it gets up to high speeds quicker at lower rpms than usually but that is usually after I've driven the car long enough to really warm up. Also it gets up to higher speeds more easily. Initially, after a few min of warm up, it takes a bit of effort to get it accelerating off the line.
My car has 140,000 miles btw. Use 6-20w synthetic oil by royal purple
Anyways, I recently had a Diagnostic test done on my car due to a check engine light and they said I need the following:
-a new upstream o2 sensor
- fuel induction service done(never been done on my car)
-new set of NGK iridium spark plugs(OEM)
- and I might need a new engine air filter as well(not part of the diagnostic but it has never been checked in a long time).
Based on these symptoms, if I resolve all these problems, what performance gains will I get in terms of acceleration? Will it be slightly and noticeably more quicker and responsive?
The cheapest, simplest and most effective improvement would have been to replace the air filter which you stated has been ignored. I can almost promise you the oxygen sensor was not faulty, just the idiot doing the diagnosis.
Also, why haven't you stated the code number (s)?
Only slightly noticeable acceleration increase. Smoother. Better mpg.
Honda Element and performance is a wet dream you're having jojo. Just drive the damn thing.
- What results will I notice once i replace the o2 sensor in my car? My car is a 2003 Honda Element Ed awd auto. I've had a check engine light on my dash for a while and I brought it to a mechanic for a diagonistic scan and it comes out to be a bad o2 sensor. My inspection is due in a few months and I'll have to get it replaced But my question is what symptoms will having a bad o2 sensor do to my car? Will it affect off the line acceleration, will it affect acceleration at any speed? Will it affect my cars gas mileage and top speed?
- How urgent is a P0420 code on a honda odyssey if there are no symptoms? I know I have to get it fixed eventually but how much time do I realistically have before the vehicle stalls and is not drivable. Any advice or suggestions would great.
- Suggest me a 125 cc bike with style that would give me 50+ milage in city rides? I'm a sales person so milage should be 50+… Don't suggest me Discover/pulser… Does honda stunner cbf self start creates problem during winter?
- How much of an increase will I get from fixing these problems in my car? My car has a faulty o2 sensor, along with a needed fuel induction service and NGK iridium spark plugs l. And a new air filter. 2003 Honda Element awd 4 speed
