Oliver Has a Cold

BrownDog · 14-09-2013, 11:48 PM

The car has been a bit sick lately, loss of power, slight miss at various points on through the rev range under load, a horrible tendency to shudder down to 500 rpm when I come to a stop then come back up and the fuel usage has gone up a little bit, may be a bit of useful info by saying that the plugs have a carbon build up which apparently indicate over fueling

I know it's time for a service, like a new air filter, oil change, defenitly new leads and gearbox oil. Maybe clean out the IAC as it normally fixes the idle issue for a bit. How would I clean an 02 sensor

Been playing with the TPS sensor which seems to change where the miss is at, how would I test and adjust that properly

All three dizzys I have put out a really crappy spark at the plug and of the dizzy if I hold the plug just off the dizzy cap, so thinking electrical fault somewhere

Also with timing there is two marks on the harmonic balancer, which one do I use

For once I'd like the car to run properly so any and all help is appreciated

Im having almost all the same issues as you

loss of power, missing when under load and the same drop in rev (round 500) when comign to a stop.

as of yet no solution though. :\ ill post here if i figure anything out

The idle problem when coming to a stop is the IAC valve, needed a really good serious clean, as for the the miss under load and all that it sort of just dissapered after a full tank of ultimate fuel and a bottle of octane boost and engine clean so maybe try that

I'll give that all a go tonight.

Yeah, i've noticed as she gets older, she gets more sensitive to what fuel i fill up with ahha.
