Greetings! I’ve enjoyed reading other people’s threads for a while now and learned a lot from you guys … I really appreciate and respect the knowledge shared here. After spending the last several months fighting a Volvo issue and reading every thread I could find on the topic across several forums, I decided to ask my question directly.
My Car:
’91 Volvo 240 B230F (non-turbo)
The Problem:
What I’ve Done:
My Skill Level:
I’ve owned this car for 5 years and my dad bought it new in 1991. I’ve worked on this car all my life and know it pretty well; general maintenance as well as the occasional bigger project. This issue has me stumped though and I’d appreciate any ideas.
Let me know if you need any additional info and thanks in advance for the assist!
Cheers,
Garrett
My Car:
’91 Volvo 240 B230F (non-turbo)
The Problem:
- Going back ~1 year, I started having random instances where my Volvo would be reluctant to accelerate. I would step on the gas but the acceleration would take a moment to fully “catch.” No big deal.
- In June of this year (2017) my main fuel pump died on a road trip and was replaced by a mechanic.
- Immediately after the fuel pump replacement, I started having more trouble with acceleration and even stalled multiple times when rolling to a stoplight etc.
- When I arrived home in early July, I took the car to my local mechanic (great guy ... only works on volvos) he fixed the in-tank pre-pump and we thought the issue was solved … it wasn’t!
- On the way home from the mechanic, the car stalled 3 times while traveling at ~40-50mph. By stalled I mean, total loss of power while my foot was still on the gas pedal. I could get the car started again but only with a lot of gas feathering and patience.
- Once home, the car has been very reluctant to start and will stall when the accelerator is depressed with anything more than a very gradual pressure. NO power at all in acceleration.
- 3 months and lots of DIY work later, my beloved Volvo is still very reluctant to start and will only idle for 5 minutes before the engine starts shaking heavily and stalls. Can’t even get her on the road to get to the mechanic.
What I’ve Done:
- Replaced fuel pump relay
- New main fuel pump (by mechanic in June)
- Repaired fuel pre-pump
- Cleaned Engine Idle Control Valve/Switch
- Checked/Set throttle switch
- Cleaned Throttle Body
- New Air Mass Meter
- New Fuel Pressure Regulator
- Checked/Cleaned fuse connections
- New spark plug wires (plugs are <1 year old)
- New O2 sensor
