O2 sensor check

[Paul Whyte]

Thanks for the info, much appreciated.

I shall try testing it over 5k rpm as you suggested.

My car seems to idle a little fast at times, especially when i come to a stop (say at traffic lights) after a high rpm run.

It is also running a little rich apparantly which is causing the high emission levels during my recent test,

I was told this may be the sensors, however I am not receiving any error codes. I had holes in the exhaust but these are fixed. The high-ish reving ad idle seems to be a little worse since these have been repaired, Any other ideas? I have checked airfilter and shall replace the sparkplugs soon through matter of course, I assumed the O2 sensors may be to blame, as fuel economy seems a little low, averaging around 32 miles/gallon. Is this normal?

The car is running fine though, starts fine and is causing me no real problems except a slightly high idle, generally 1k rpm, sometimes it revs up to 1.5rpm and then drops again. It makes the car infront think I am getting impatient

Any ideas would be gratefully received.

Many thanks.
Paul.

check your throttle body and idle air controll valve for coking [crud]. if it failed a smog test i would think it will force a CEL . an exhaust leak can fool the 02 sensors making them think the car is lean so they richen the mix. look at injector on time [mil/sec] ....you will need normal specs to compare

Thanks again for the info,

Much appreciated. Will see what I can find.

Next big job is replacing the starter motor, as it is noisy on startup, clogging up on the benedics, I have a replacement and plan on reconditioning the old one to sell on ebay I shall check the throttle body and idle air control valve as you say.

Cheers
Paul.

ive read people remove the starter,lube it and put it back in

[Paul Whyte]

Yup, I have instructions on how to dismantle and lube the starter, its the same starter motor as a VW apparantly. However I bought a cheap one on Ebay, that way I can do a direct replacement, and it doesn't matter too much if I drop a spring or screw down the back of the cooker while I am reconditioning it, I can still get to work the next morning haha.
