Hi chappies,
Been having some problems with my car lately. 2.0 ltr Zetech 04 focus.
Idle seems a tad low (like 650rpm ish). And initially power from 1k to 2k was lumpy (misfire?) and the car felt sluggish, this rectified itself after 2k revs.
I took it back to the dealer as it was in warranty, he said one of the sparks wasn't firing properly and replaced them all. Problem solved.
Now the problem is back, but it's all the way through the revs now. Today I disconnected the maf, which rectified the problem though the car was less smooth. After that I took the piping from the back of the maf to the engine off and had clean inside the maf. Also unplugged and pushed back in the HT leads. Car seems better now.
Could the MAF or HT leads have caused this? If it returns what's my next port of call.
I also undid the airbox to try and get at the filter, but the rear-centremost bolt wouldn't undo. On closer inspection the nut attached to the housing has come free, and no matter WHAT i did I couldn't secure it to undo it. It's a pig to get at, I got a good set of pliers to it and tried to undo it but to no avail. Any ideas how to get the ****er off without massacaring / replacing the airbox?
ALSO. when idling the lights dim significantly and sometimes the engine struggles, it's stalled on several occassions because of this. Also when I turn on heated windscreen, lights dim signficantly. When the car idles the lights interior/exterior are very dim, and the fans slow on the AC. Giving it some revs rectifies this. Is this normal?
