I have a volvo engine 5.7ltr V8 1985, She idles smooth as you like, and in trolling speed she is a gem, but when you go to thorottle her, she gets upto 2500RPM and wont go any further, and sounds like she is missing on some cyl's?<br /><br />The temp is fine, everything i s fine says my dash, but she wont get over 2500RPM, i checked all the plugs were in place etc..<br /><br />Any help would be grateful<br /><br />to add, she is getting pleanty fuel, and spark from the coil is bright blue..<br /><br />would it be the condenser?<br /><br />Or dodgy lead or plug.. i am hoping it may be something simple to fix
