ive bin averaging about 200miles to a tank which before my cambelt change i was getting near 300...

only thing that has bin done was the timing belt so im putting it down to this? unles its coinsidense...
whats the average price to get timing sorted???

it takes abit to get it started couple of turns
can sometimes idle funny but did this before i had belt changed...
takes more revs than normal to get it going otherwise stalls...

i want to get this sorted because its costing me alot in petrol

if im better of just taking it to a garage could people possibly recormend a garage in my area brigwater/yeovil as im not a fan of TSR fairly new to driving so havnt really got the chance to try many garages and my dad uses main dealer im a student

many thanks matt

You need to check your timing ASAP. Sounds like it's out a tooth somewhere. If it is it will burn out the valve seats.

The sender costs about Â£11.00 with the rubber O ring. I replaced mine last weekend with the thermostat because of the engine running way too cool. The coolant sender is under the dizzy, it has a yellow plastic ring around it and a 4 wire plug attached to it. I drained the system on mine by disconnecting the bottom hose, I knew I'd just soak everywhere if I didn't

I was told you should disconnect the battery first and leave it at least 30mins to reset the ECU before reconnecting it back up.

o rity well im replacing my dizzy cap n rotor arm is pretty nakered so im replacing that 2mor...

I'd replace the dizzy cap and rotor first and see how it runs. The thermostats and O ring are pretty cheap but the only reason I replaced my stat was because I wasn't sure it was working well. Now my car warms up really quickly with the temp guage never moving off 90C.

ok well my cars doing the same thing wer it wont hold 90 so i wrecon for hte sake of Â£20 ill do both the stat and senda... hopefully get it done by end of week because its costing me a bomb in petrol and i cant stand the crappy performance
