Rover 45 1.6 flat/underpowered
Messages 1 to 20 of 35.
any help or things to look for from you experts would be greatly appreciated
Basically your air flow meter. Take this off its connect to the air filter the end piece. Once done you will see a sensor running down the middle. Okay I did this on a rover 400 diesel.Clean that sensor carefully with white spirit and cotton buds,If loads of dirt com off clean it thourghly with the spirit.Connect back onto the car and hey presto. If this doesnt sort it out change the fuel filter. A word of caution these mafs are bloody expensive 30 40 pounds so be careful
changed the air and fuel filters again no change. just wont seem to pick up until 4000rpm, anything below and it just struggles like your in a gear too high
how its been driven in the past. Its low mileage correct 55000. So it sounds like its been driven to the shops and back. This could be the problem,these engines are high revers. What im saying is give it a blast down the motorway. My Rover ok its the 2.0 td is like a bat out of hell. Mainly because it started life as a company car. It has 168000 on the clock and will fly past anything on the road. I also drive it on the motorway say once a month. Try it it may need it to flush this underpower out
to be honest, i have been thraping it alot this last week and i it's started picking up at around 3500rpm now instead of 4000rpm so maybe it is starting to improve. did think it could have been a throttle switch or crank sensor or cat, but don't know much about them. thanks for your advice so far..
especially the petrols. Take the oil cap off if it looks like milkshake thats head gasket. I have a feeling the head is on its way out. Another sign is excessive moisture in exhaust. I have had one done before for over 250 pounds. You can also upgrade the head gasket to a sronger one. You are defo losing compression clasic sign
well, checked the oil, it is milk free and nice and clean still at the correct level, checked the water and again still the correct colour and quantity. heard that these suffer with head gaskets, guess mine is possibly on its way then, i will monitor the oil and water for a few weeks
what about fuel filter fuel pump etc get these checked. Its either not enough fuel going through. I hope this is the problem. Ok try this this will tell us if its a fuel problem on the pipe attached to fuel filter you will see a large bulb prime that I mean pump it it must be hard. Then start the car and drive Adverts Currently On Preloved - Place an ad here for free
Just disconnect the wires then take it for a run. If its better its the maf
you say disconnect the vac hose etc if all is fine what should reaction should the engine have??? had a vauxhall once that kept going in to "get you home mode" but that really was flat, this feels like it is just missing it's low end torque....as soon as it hits 4000rpm she starts to pull well and still does 90mph comfortably just as long as you keep the revs up, it's like when you floor it, the timing doesnt get advanced enough...like an old distributor fault. will try these suggestions out tomorrow
removed the vac pipe which made the car run rough, i sucked the pipe which made the car rev each time so i assume that is all ok. drove the car with the MAF disconnected but noticed no real difference low down, it was still flat but def more underpowered higher up the revs. finally... the car has no fuel bulb primer, the metal fuel pipe comes from the tank to the bottom of the fuel filter, then out of the fuel filter top and straight to the fuel rail.
do i still need to change the ecu temp sensor with these fitted and if so where can i find it??
This flat spot may be timming you haave had the belt done right, Okay im going to ask me mechanic mate on this one. Will have a reply I feel like I know this car very well. But you have to admit we are getting there. Have you checked all the leads coil and everything. We will get this bloody car fixed. So now its got a flat spot on low end. I like all the advice we are all getting here so thanks to everyone
Get the engine up to running temp then rev it up high over 30 minute period. Then give it another blast. going down and up gears. My mate says at least try this again. As we stated earlier I think this could be the problem, Its been driven to carefully in its younger life. Something needs to be flushed out. On a previous car I had well a Clio RSI. I was always blowing the cat. Give it a tap underneath does it sound like its broken up inside. Or better still take it off then try the car. Oh yea dont forget to get another one for the MOT. And I did not tell you that lol
