16v 1.8 Strange Problem

[Ad2408 0]

Hello All

 

Hopefully some of you lot can help.

 

As above really, my girlfriends car (1989 Valver 79,000 miles) is pretty reluctant to rev when you first start it in the morning. By this I mean it starts brilliantly, drives fine but if you put your foot down it seems like the revs just don't want to climb.

 

On top of this it also doesn't seem like the revs drop as quickly as they should. i.e. you let you foot off the accelerator and it takes a while for the revs to drop off.

 

Hope you can help

OK.... Next question, how do I set up the mixture correctly?

 

Thanks for the answer by the way!

Hi

Sounds like a sticky acelerator cable

OK..... Another 2 questions(!) How do I......

 

1. Set up the mixture correctly?

 

2. Sort a sticky accelerator cable?

 

Thanks

1. get an MOT station/garage to do it unless you have an accurate gas analyser, the steps are detailed in the Haynes manuals covering either the K-jet injection system or the passat 88-91 manual, possibly in the mk2 golf manual if it covers the 16v engine.

 

2. replace the cable, or give it a bit of a lube, but once they wear they really need replacing, your problem doesn't really sound like a cable though, but a new one feels so much better and due to the 180- deg turn they make they do wear badly.

 

 

thinking about it, perhaps you have a cold start injector or warm up regulator problem, again, haynes does provide a checklist for each of these including resistance values etc. you'll need at least a multimeter though.

there's a good guide to setting the mixture on your 16v written by the Haywire. Use the search.

could it be a engine speed sensor?

 

or were these not fitted as we are going back some,

 

just at work when we get audi's and vw's in and there reluctant to rev, usually the speed sensor, altho they do tend to idle rough or, sound like a chug boat.

 

just an idea!
