My '87 Turbo-T has been experiencing a weird problem lately. It feels like the engine is missing or a plug is fouled up, the engine is not smooth and it lacks low end power. And also every now and then it blows alot of white smoke out the exhaust as if it were extremely rich. So we started by changing all the spark plugs; same problem. We checked the rockers, all were fine. We switched the coil pack; same problem. We checked the compression, it was fine. Checked for vaccumn leaks, found one and repaired it but the problem is still present. The car doesn't have a MAF sensor anymore since we installed a new DFI computer last year. The tuner checked the DFI and said it's fine. Through all this checking and test driving we noticed that the problem is not always present. The problem is present 90% of the time but every now and then the problem will almost disappear; it smoothens out, has good power and no smoking.
Has anyone out there experienced any problem like this? Anyone have any idea what's wrong? Any help would be appreciated. Obviously the car is not stock, it has a DFI and complete engine rebuild with a T60 series turbo. But all the work was completed over a year ago and it's been running fine until the above symptoms just started up.
