MSnSE running badly after winter lay up - why
Hello,
My Vauxhall Redtop has always run really well however, I started her up this week and she is totally over fuelled and running like a pig. I have
ordered a new temp sensor but wanted to check if it is possible that anything else could have been altered in the settings after a long spell without
activity?
Cheers

You are probably on the right track the CTS, MAP and TPS are the main inputs at start up and once the engine warm the Lambda
Really a case of looking over everything very carefully to check that no connector or vacuum pipe has got disconnected. Other than that the only
other thing is the fuel pressure.

Same as above, my TPS was stuck to 100% load so the advance was not correct for starting.

OK, thanks.
Dummy question time, how do I fix a gummed up injector?
I presume with the TPS I just remove it and check that it is free?
Cheers

Personally id just datalog a couple of minutes of running to check what's reading funky. More likely to be an injector than a sensor to my mind
but either is possible.
If its an injector it may free up with a heat cycle but by then you could have damages to engine so worth removing and having them cleaned. Butv
datalog first, it is the MS equivalent of reading for fault codes.

Only way to check a TPS is to look at the output,
With an injector only cure is to replace or send it away for ultrasonic cleaning and back back flush.
A sticking over fueling injector will only over fuel one cylnder,
