156 v6 - losing power, driving rubbish and not going above 4000rpm
Hi guys, wondering if any of you experts can possibly help and bring an old girl back to life. I've got a 99 2.5 v6 which i thought needed a new MAF for a bit of time. It would hit a lack of power at 5000 revs and was slowly losing a bit of kick so took the MAF out and drove it around and she drove a lot better. Also would drive absolutely crap coughing and spluttering during the 1st minute driving from cold. That was a couple of months ago, for reasons I wont bother going into, I havent been able to drive the car for a couple of months (was stuck with a 1.6 megane, don't ask).
Got her jumped started last week as battery went flat, drove her around for a bit and she was driving as if she had bronchitis and dying. Wasnt going above 2000 revs, coughing spluttering, no zip e.t.c. Ordered the new MAF, went to fit it yesterday at the same time as I was changing battery but didnt have 5 sided torx bit so couldnt do it. Thought I'd see if a throttle reset would do anything, took her out for a drive and was displaying same symptoms as last week. HOWEVER she started to drive better after about 15 mins, can now get up to 4000 revs but seems like its limited there. Also went on motorway, got up to 70 then started losing power, would go down to 40/50 and wouldnt want to go back up. In town shes bearable now but I'm thinking could be more than maf. I can only lightly hit the gas, if I go too heavy she does't respond. I'm hoping the new MAF will sort it but I think it's more, any of you guys have any ideas? Thanks. (sorry if any mistakes, wrote this on the phone). Cheers guys.
