running a little hesitant. Ideas Please!

[bassman]

I took me RX7 out the other day and as I put my foot down to over take, as the revs got up it was hesitating (lumpy).

Now, I haven\'t been driving it much over the last few months, probably 1 hour every two weeks, and also when I took it in for some paint work about a month ago, they flooded it, obviously because they were just starting it up and moving it regulary.

i just wondered if the hesitancy could be down to Spark plugs which have been wet even though they were installed twoo weeks before they flooded it?



any ideas?

Sounds like the Sparkies, get them out and have a look to see if they have been fouled via the flooding you encountered

Change of spark plugs.

i had the same peoblem, first things id check are the following :

1. Spark Plugs (£45)
2. Fuel Filter (£35)
3. Lambda Sensor (£40)

these things should be available from autofactors.  My problems was the lambda causing the lumpy drive.  Now that its been replaced, it drives like a dream

[bassman]

Thanks, I\'ll check all these

ahh, the lambda, i get the same sometimes. if i give it some beans its well, as it was described, lumpy a bit, then kicked in and waaaaaaheyyyyy.

would a hot cat knacker the lambda, my cats v.hot and blowing. ive got another coming, so will see if this has any affect.

You could try plug leads too - I had very similar issues with mine which a set of brand new plug leads sorted.

got new plugs the other week when i couldnt start my car after not driving it for a few weeks.  leads it might be but i\'l see wot happens with the cat....

cheers

[simonman]

nikp, you say plug leads. was the hesitancy only from cold engine to hot?  or only when it got hot?

[nikp]

Was with both. Hot and Cold

Actually, when i think about it, i only noticed it when hot, but that\'s because i took it easy when it was cold. You don\'t wanna boot any engine when it\'s cold, so i kept it easy.

[simonman]

ummm. will have to try the leads too.  can i buy any silicone lead or has it got to be the rx7 leads??

[simonman]

it sounds like the same problem me and bassman have.  i may have to book my car in at WGT.

inder the drivers seat, under the carpet, there is a braided wire going through the floor. is this the wire for the cat heat switch?
