Technical Stalling Punto GT.

[FPGT3]

Hi, Anyone Help ? My Punto Has Just Come Back From A So Called Fiat Specialist Who Said We Think We Have Fixed Your Car Quote By Simply Changing The Lambda Sensor But Suprise Suprise It Has'nt Fixed It. Bloody Muppet. It Runs Poor Also But Usually Stalls When Approaching Junctions Changing Down A Gear. Anybody Shed Any Light On The Matter ? Cheers.

Hi mate,

What does the car idle like? (cold and hot), and have you modded the engine in any way?

Cheers,
Alan

When The Engine Starts Up From Cold The Automatic Choke Only Seems To Be On For No Longer Than 60 Seconds Before The Revs Drop To About 850-900 Rpms. You Can Hear The Exhaust Pop At Idle. The Revs Just Bounce Up And Down Slightly Both Hot And Cold. The Car Has Had The Following Fitted To It:- Bleed Valve, Induction Kit, Seb 2 Chip, Power Boost Valve, Garret T25 Turbo, Performance Cat Fitted And Of Course Dump Valve. None Of Which Has Been Done By Myself As Already On The Car When Bought. Lee

Ok, has it ran poorly since you got it or has it developed over time?

When your driving the car, does it run poorly when on boost?

 

[FPGT3]

It Did Judder Quite Badly When I Drove It Home On The Motorway Now And Again When I Was Trying Not To Boost It. Usually When I Was Trying To Keep It At 70mph. But Later Found Out A Pipe Had Come Off The Turbo Which Was Causing It To Boost Over 1.5 Psi On My Additional Gauge. God It Was Quick Though. It Has Been Getting Worse And Worse Since I Have Had It Though. After The Pipe Was Re Connected It Has Been Boosting Fine Until The Other Day When It Had A Slight Pause In Power And The Injection Warning Light Came On For A Few Seconds Then Went Off Again.

Can you swap out the chip to original and have you cleaned the throttle body recently? ICV is also worth a look whilst your at it.

Sorry Dont Understand What You Mean By Icv. I Dont Have The Original Chip Im Affraid. Funny You Should Say That About The Throttle Body As I Cleaned It About An Hour Ago Just Have Not Had A Chance To Road Test It Yet. Cheers

Hi mate,

Sorry by ICV I meant Idle Control Valve. Fingers crossed!

I Have A Receipt For An Icv Which Was Changed August Last Year But It Was From A Place Called Continental Car Breakers So Am Assuning It Was'nt A New Part And It Cost £25.
