Hi,
I experienced the following problem today. The car was already hot and I had to stop for a few minutes. When I started it again everything seemed fine but when I tried to accelerate it had no power. It would not rev past 2000 rpm. No power at all...it was struggling up a hill. I decided to stop, pulled the handbrake and waited for a minute without turning off the engine. After 1 minute I tried to accelerate and everything was fine. When the problem occurred there was a beeping from the computer but no warning light. As soon as I got back home I used my diagnostic equipment to check the faults in the ecu...surprisingly there were none...
Any ideas what's wrong?
Blocked cat/ exhaust maybe? The best way to check this is to bolt the exhaust off at the manifold and take it for a noisey run, make sure you do this at a sociable hour though
All I can possibly think of is a loose connection on an injector or a temporary fuel blockage that has thrown the ECU into limp home mode... Although I would have thought that at least some record of the the fault would be there when running the diag. Some cars don't though
Check the connectors and give it a nice fuel treatment as a preventitive measure. Redex or any propriety stuff will do.
It maybe because as you have already said that there was no fault codes m8 to lead it to being a faulty MAF... The usually do throw a few up on Diag.
If the car is running right, then it's highly unlikely to be the MAF, they don't cure themselves, they just get worse.
Many, many owners get a "phobia" or "hang-ups" about the dreaded MAF issues...
In reality.... They often change them based on advice from others (not their money they are wasting) when quite often, a good clean of the plug contacts or at worse, cleaning the MAF itself would suffice... 20 minutes worth of your time or £120.00+ for a new part. I know what I would try first:thumbs: After all, of course it does the trick... It should do as it's a new part! Yet they don't actually try cleaning the old MAF and trying it back on... DOH!
Don't worry about the MAF just yet m8
my faulty crank sensor never made the car cut out just a misfire from cold its only a sugestion but i dont think they are as simple as cut out for a while when hot in my opinion they can behave in different ways when faulty
The engine kept running without any problems. It was only when I tried to move the car that I experienced the problem. It was hard to move it at all. I would say it looked like a misfire. I have experienced a misfire in the past but it threw a fault in the ecu and the engine management light was on all the time.
