It could be a number of things mate It could be your ignition system or down to a vacuum leak or bad fuelling. What is the exact symptoms does it hesitate to start at all? does it cut off on its own?

Mine felt sluggish a while ago, especially around 70mph in 4th and 5th would make boost but just not accelerate much, also had a random misfire now and again.

Changed spark plugs to copper ones and seems to have cured both

starts fine - drives pretty decent

when giving it some revs - seems to make me change gear -

notice it more in 3rd 4th tbh when wanting to let it rip

in 5th also it should just fly but something holding it back

il put sensor in today and buy some new spark plugs - thats prob what it is

if no change will let you no

[starletezy]

keep us posted mate

You done diagnostics check!?

^^^ do this and also check map sensor/connection, distributor, plugs, wires and 02 sensor/connection

vehicle speed error? - assume this was saved from the other day as speedo was not working - we fixed speedos so i imagine that was just a saved code - -

no other codes?

3 or 4 pin TPS?

[haggis]

did you change sparks and 02 sensor ?

mines kindof doing same but think im running really rich

some guy had same problem tried everything and turned out his king leads were shot. he went from 129bhp to 170bhp no lie ( obviously had all the gear to go 170) but jist shows you how important ignition is

let me know if you sort it man as i want to know

[haggis]

any joy mate

[NICKYG2X3]

yes problem resolved. car was overboosting to fuckk. and was just not going any where in higher revs adjusted actuator

your prob could be any of the above - distributor / spark plugs shot. etc
