Hey, Its been awhile since I have been here or worked on my Volvo, as I am finishing my degree. But I can't ignore the hard starts and crappy running anymore. Here are the symptoms my 2.3Ti is suffering from.
- Cold starts - It takes 4 tries to get her to run. I find that it sometimes goes but shudders at a low RPM then dies. It feels fuel related.
- Poor return to idle - When driving and I put my foot on the clutch instead of it returning to idle it dives to 3-500rpms, shudders a bit, and then comes up to 8-900rpms for idle.
- Poor gas mileage - I am not sure what it is, but I know it is worse and I also get some black smoke on heavy acceleration.
- Poor performance - I get surging and at about 3000rpms it actually bogs down a bit and the power is decreased.

I have recently done...
Plugs, rotor and cap, cleaned TB and IAC, intank pump, main fuel pump and filter and new FPR.

Any Ideas....I am thinking leaky injector(s). Would this cause all of these problems though? What is the best way to clean leaky injectors as I have priced new and they are expensive.
Thanks, Grant.
