Hi I have a 98 ek4 a few weeks ago I noticed that when the throttle is pressed about a quarter of the way that the car seems the hold back as if I'm driving with the foot brake on so I ran a test by bridging the terminals at the ecu and the engine light flashed 7times. so Googled the fault code and came up as the throttle position sensor so it has been changed, the map sensor, fuel filter, leads,and plugs any other ideas of what the problem could be? The car is driving fine when the throttle is engaged half way or over and is pulling well and vtec kicks in as normal I'm baffled was thinking would the dizzy cause this.
 
Yes took both positive and negative off and left for a while and then refitted
 
I checked after putting the battery terminals back on and it was away just abs codes showing will check again tomorrow
 
Checked the codes again and there are no engine faults found just abs codes
 
Tested the tps with a multi meter and it's reading perfect voltage so I've ordered a new dizzy and rotar to see if that cures the problem
 
Hi back again problem still here I've changed ignition coil,dizzy cap and rotar,fuel filter, cleaned the throttle body and iacv,changed lamba sensor,tps and map sensors any other ideas
 
When you say throttle is pressed about a quarter way... is there a specific rmp range you have the problem?
 
Do you think that is what it could be will it have done any damage to my engine
 
If the idle is that low, there may be a vacuum leak. Check the hoses for damage.
 
How many vacuum hoses are there and where is the location of them please thanks for all the help appreciate it
